Since I'm living in Sacramento right now I've also thought of heading over that way, but the campgrounds and residents are definitely iffy. All commercial, no state parks or hiker/biker sites. I pedaled through one that was south east of the lake last summer on a long day ride and it looked pretty bad. I think i will stick to going west up into the foothills to camp. Can't wait for cooler weather and the crowds to leave. I miss camping in the redwoods west of the bay area.
