Can you live off-grid in Jasper County, Mississippi?
87
of 100
Good with caveats
Yes, with two things to plan around. Rain is plentiful, about 59 inches a year. NOAA counts about 11 strong tornadoes a decade within 25 miles, so a storm shelter belongs in the plan. NOAA counts two hurricane-strength storms within 50 miles since 1975, so build to the wind code and plan for long outages.
