Had to go look at a solar powered radio repeater for a logging company today. Five miles off the nearest plowed road then a hike up a mountain in knee deep snow. They gave me the use of a skidder and even let me drive. 18" snow, small trees, ditches didn't slow it down but the trail to the top was to steep and narrow. The hike up the mountain sucked, I'm too old and fat for this stuff. Panels and batteries were working fine, radio was dead.
