Prepper Assessment

Living in this area offers a predominantly rural experience with a low population density of 7.4 people per square mile, promoting a sense of remoteness. The climate features an annual mean temperature of 43.7°F, with a growing season suitable for USDA zone 6a. Water availability is moderate, with 19.6 inches of annual rainfall, but the dry sub-humid classification suggests careful management is needed for self-sufficient living, particularly in terms of crop selection and irrigation.

The county faces several natural hazards according to FEMA data, with cold waves and winter weather ranking high at 89 and 82, respectively. Wildfire risk is also notable at rank 81, which could impact land use and safety. While the violence percentile is moderate at 54, indicating a relatively average level of safety, the cost of living remains reasonable, with a median home price of $115,900 and effective property tax at 1.53%, which may appeal to potential residents.

This county could be a good fit for those seeking a quiet, rural lifestyle and who are prepared for the challenges of cold winters and potential droughts. Homesteaders with experience in managing colder climates and limited water resources may thrive here. However, those who rely heavily on broadband access or prefer urban amenities may find this area less suitable, as only 72% of households have broadband subscriptions, which could impact connectivity and access to information.
