I normally like to camp at Palo Duro Canyon on my way west to CO or Utah. The camping spots were all reserved on this trip though. I found Thompson Grove picnic area through this site, and didn't know what to expect. It ended up being an easy place to eat and car camp for the night. I wouldn't recommend it for anything other than a pausing point, though. There were bathrooms on site, and they seemed to be pretty well kept. I'm a solo female camper and traveler, and I felt safe being there.
