Can you live off-grid in Harding County, New Mexico?

Significant challenges
Possible, but water will be hard. Only about 16 inches of rain falls a year, so you will rely on a well (near 80 feet here) or hauled water. The sun is strong, about 6.4 hours of full sun a day, so a smaller solar array covers a household. The ground is mostly flat and drains well, which keeps building simple.
