We do a lot of Tx state parks. When we use one we haven't been to before, we usually drive the place after we check in and, if we find a better spot, we just stop at the park host and they radio the gate and make sure no one has booked that spot. Then all you do is set up camp then go back to the gate and update everything. I find if you come in early on Tuesdays you pretty much have your pick of sites. I usually avoid weekends since I don't like people all that much. And water. Idiots are drawn to water. It's a proven fact. Come to think of it....I need to move to the desert.
