As stated before... heading to Tucson from Fla.. on I-10... what about the State Parks thru texas........heard they weren't the best....anything good good around fort Stockton?
Travel a few miles further west on I-10 and take State 17 south. Short trip down the road to Balmorhea State Park. A ways farther south you'll find Ft. Davis State Park. Or divert north off I-10 up to I-20 and try Monahans State Park - but be warned, because of the gas & oil boom it may be impossible to get into that park without reservations.
