I could not find any camping areas, so I stopped and asked a ranger doing some clean-up in the parking area by the store. He pointed out a few areas, and said there were two camping areas marked down the road further.
First I checked the area "at the end of the parking lot" - I didn't see anywhere I'd want to camp. I guess it was better than a WalMart parking lot, but I assume people pay to camp here. Next we drove out - back onto the road and visited the first campground he mentioned.
I love it when the sun comes out and shines through the clouds - this was taken through the open window as I was driving:
