Hula Ville

Route 66 – Victorville, CA

After retiring as a ‘carny,’ or carnival worker at the Venice Pier and Santa Monica Pier, Miles Mahan (1896-1997) began building Hula Ville in 1955.

Wine- and beer-bottle tree sculptures adorned Joshua trees and wooden posts. Desert sandblasted wood signs held poetry and prose; dolls, award statues, and other found objects were displayed outside. A homemade miniature golf course bordered by half-buried bottles was included in his residence, as well as a pickup truck camper and a pickup truck camper without a truck. There was no charge, and donations were accepted.

Mahan also erected a large dancing hula girl sign at the entrance, a business discard he rescued and repurposed. The crude hand-lettered sign beneath her read: “People travel through the state, how little will they know her fate, for the traveler who’ll ever be the wiser, the Supervisors saved her life.” Busses traveling to Las Vegas from Los Angeles would stop, and Miles would entertain them by dancing on his little wooden stage, and they would leave tips. Even in his eighties, he was still able to dance. As much as he enjoyed guessing people’s weights at carnivals, he enjoyed watching Hesperia grow into a city. His poetry and books mention the many people he met along the way, with whom he loved talking about real estate. Whiskey Pete and Scotty from Death Valley were his friends, and Miles was quite a storyteller. These were all true stories. He appeared on the Johnny Carson Show as Johnny invited him back due to his outspoken personality 2 or 3 times. They would send a limo to pick him up and return him.

In 1995 Miles Mahan moved to a convalescent home and died on April 15, 1997. In September 1997, Hula Ville was demolished.

Jackrabbit Homesteads

Jackrabbit Homesteads, a unique phenomenon in the American Southwest, hold a significant place in the region’s history and culture. These small, rustic cabins were built on public lands in the mid-20th century. They offered settlers the opportunity to claim a piece of the desert and forge their own paths. We will explore the intriguing story behind these homesteads and their enduring legacy.

The establishment of Jackrabbit Homesteads dates back to the passage of the Small Tract Act of 1938, which aimed to encourage settlement on federal lands. Under this act, individuals could claim up to five acres of land and build a dwelling upon it. Many of these homesteads were constructed between the 1950s and 1970s, attracting individuals seeking a simpler, off-grid lifestyle or a weekend getaway from the hustle and bustle of city life.

Jackrabbit Homesteads were typically modest, one-room cabins constructed from inexpensive materials such as concrete blocks or plywood. These structures were often sparsely furnished, reflecting the self-sufficient nature of the homesteaders who built them. Although lacking in modern amenities, these homesteads provided a sense of freedom and a connection to the surrounding natural landscape.

Living on a Jackrabbit Homestead required resourcefulness and willingness to adapt to harsh desert conditions. Homesteaders relied on rainwater catchment systems and solar power; many grew their own food or raised livestock. The simplicity of this lifestyle allowed individuals to reconnect with nature and find solace in the vast desert.

While Jackrabbit Homesteads have passed, their legacy lives on. Many homesteads have been abandoned or repurposed today as reminders of a bygone era. Some have even been transformed into art installations or preserved as historical landmarks. The National Park Service has recognized the cultural significance of Jackrabbit Homesteads and is working to preserve and document these unique structures.

For those intrigued by the allure of Jackrabbit Homesteads, there are opportunities to explore and experience these historic sites. For instance, Joshua Tree National Park in California is home to several preserved homesteads that offer a glimpse into the past. Visitors can wander through these time capsules, imagining the lives of the individuals who once called these cabins home.

Jackrabbit Homesteads are a testament to the human spirit of resilience and the desire for independence. Scattered across the desert landscape, these modest dwellings tell a story of determination and self-sufficiency. While the era of homesteading may have faded, the legacy of Jackrabbit Homesteads continues to captivate and inspire those who appreciate the allure of a simpler way of life.

Controlling Local History: The Practice of Marginalization and Banning People

Introduction:

Local history shapes community identity and collective memory. It preserves the stories, events, and heritage that shape the present. However, in some cases, the practice of controlling local history and banning people from it has raised concerns. This blog post explores the implications of such practices and their potential consequences for communities.

1. The Power Dynamics of Controlling Local History:

Controlling local history involves the selective interpretation and presentation of historical narratives, often influenced by those in power. Controlling the narrative can emphasize certain perspectives or events while suppressing others, resulting in a skewed understanding of the past. This power dynamic can lead to the exclusion and erasure of marginalized voices and communities.

2. Banning People from Local History:

Banning individuals from participating in local history recording, sharing, or access restricts collective memory and perpetuates exclusion. This exclusion can occur for a variety of reasons, such as political dissent, social status, or cultural differences. However, by denying individuals the right to contribute to, learn from, and engage with local history, a community risks losing valuable insights and perspectives.

3. Implications for Communities:

When individuals are banned from local history, the community as a whole suffers. The diversity of experiences and perspectives is diminished, resulting in a narrow understanding of the past. This can lead to a distorted sense of identity and an inability to learn from past mistakes or appreciate the contributions of all community members. Furthermore, the practice of banning people from local history can perpetuate social divisions and hinder unity and cohesion.

4. Promoting Inclusive Local History:

To ensure a more inclusive and accurate representation of local history, it is crucial to adopt practices that encourage participation from all members of the community. This can be achieved through initiatives such as oral history projects, community-led documentation, and the establishment of inclusive historical archives. Communities can create a more comprehensive and nuanced understanding of their shared past by actively involving diverse voices.

5. The Importance of Dialogue and Understanding:

Rather than banning individuals from local history, fostering open dialogue and understanding can lead to a more inclusive and comprehensive narrative. Communities can work toward reconciliation and healing by creating spaces for conversations, sharing different perspectives, and acknowledging history’s complexities. This approach allows for a more accurate reflection of the past, embracing diversity and promoting a sense of belonging for all community members.

Conclusion:

Controlling local history and banning people from it has far-reaching consequences for communities. It perpetuates power imbalances, excludes marginalized voices, and limits collective memory. Instead of resorting to such practices. Communities should strive for inclusivity, open dialogue, and the active participation of all individuals in shaping and preserving local history. Doing so can create a more accurate, diverse, and enriching understanding of the past, ensuring a more inclusive and united future.
