Don't hear me bad mouthin' your trouble...but here in the land of fruits, nut, and flakes - a dude has to be resourceful or the granole eatin', Joan Baez music lovin', Volvo driving, REI tent campers will get every good spot.
We have gone so far as to arrive a day early, set-up the rig and drive home to work the next day. It's well worth 1 day fee to get THAT SWEET spot.
God bless Texas, but come visit California to cool off
