Computers/Networking Infrastructure:
Talked to Don about Hanksville line-of-sight service. He estimated that
power cable costs would be about $1 per foot. At 1050 feet, this is
about $1050. For the same price, we may be able to install a solar
panel and battery at the peak of Hab ridge instead. Direction
requested.

Leaky hose on water heater was sealed with silicone. Water heater was
turned on. Hot water is lukewarm at best, no different than cold water
at worst.
