On the east side of Marfa
I much prefer to camp free. And just the phrase "RV park" usually makes me cringe. But this one has tent sites and is fairly cheap. Most of the RVs are on the small end of the scale. It's not a glamorous place, but there are showers and flush toilets. And a nice, friendly, group of young people who want to feed me.
Who doesn't love an Airstream?
