I live in Denver. I sail in Maine and commute in my minimalist camper van. Returning West, I was tired and it was getting dark and a big storm was about to bust loose. I looked at my map and saw a patch of green with blue in the middle, right off the highway and headed for it. Sutherland Park State Recreation Area is on a lake formed by a dam with a small hydropower plant. There's a campground away from the water, but it was deserted and creeped me out. The other camping was by the lake. Nice breeze. $7/night. Pay at the bar/golf course club house serving the locals.
