Prepper Assessment

Living in this area offers a predominantly rural lifestyle with a population density of just 4.2 people per square mile, allowing for ample space and privacy. The climate is characterized by an annual mean temperature of 46.2°F, with a growing season suitable for USDA zone 6b. The county receives about 24.2 inches of rainfall annually, supporting diverse agricultural activities. However, the cold winter lows of 6.7°F may challenge year-round gardening efforts and necessitate adequate heating solutions.

The county faces several natural hazards, as indicated by FEMA rankings, with wildfire risk at 67 and drought risk at 63. While the area is relatively safe from violence, with a violence percentile of 54, the low disaster percentile of 3 suggests a stable environment. Housing is moderately priced, with a median home cost of $128,800, but potential residents should consider the limited broadband access, with only 61% of households subscribed, which may impact remote work or online education options.

This county is best suited for individuals or families seeking a quiet, rural lifestyle with a strong emphasis on self-sufficiency and agricultural pursuits. Those who thrive here will appreciate the affordability of housing and low population density. However, individuals reliant on high-speed internet or those uncomfortable with the challenges posed by colder winters may find this area less appealing. The hidden gem for homesteaders could be the abundant space for farming, while the potential dealbreaker might be the risk of wildfires and drought.
