If you happen to be wandering on US Hwy 77 in central Texas and are around Giddings, Tx at stopping time try the South Forty RV Park. It's about 6 mi South of Giddings. No office, just drive in and if someone doesn't meet you on a golf cart follow the signs to the honor box and sign in. Pick your spot and enjoy. Park is all gravel but no problems even in the rain(I know). LOOONG spots and abt 50' apart. Full hookup including 50A. The pool is open 10-10 but the gameroom is open 24hrs, satellite tv, pool table, coke machine, $1 bag ice, again honor system.
I'll be going back when I'm in that direction.
