Modoc National Forest
About 50 miles north of Susanville, California I camped one night in the Modoc National Forest. I took one of the gravel roads from highway 139 for about a mile and parked at a wide spot in the road. Not a good spot for solar panels, too many trees. It rained in the evening, then snowed as I was leaving in the morning. No Verizon signal.
The campground not much further down the highway was still closed for the winter. As I drove further north, I parked for a while since the snow was building up on my windshield. (More than the windshield wipers and defroster could deal with.) I check my email and continued on after half an hour or so.
