Can you live off-grid in Kingfisher County, Oklahoma?
91
of 100
Good with caveats
Yes, with two things to plan around. Wells are shallow here, near 50 feet, which keeps drilling costs down. Flood zones cover parts of the county, so look up any parcel on FEMA's flood map before you offer. NOAA counts about four strong tornadoes a decade within 25 miles, so a storm shelter belongs in the plan.
