The scary part of looking for what you haven't seen is realizing just how fortunate Texas is in the sheer number of State Parks, Historical Parks and former State parks, and that doesn't even touch city, county or private parks.
At this point there are 11 "parks" in the Big Bend country alone
Balmorhea,Big Bend SP (of course NP too), Davis Mountains, Fort Lancaster SHS, Devils River SNA, Fort Leaton, Franklin Mountains,Hueco Tanks, Mugoffin Home SHS, Monahans Sandhills, Seminole Canyon and Barton Warnock. WOW.
Some of these are primative, some historical some just plain fun.
So maybe you and I or we all need a road trip
Then again my temp avaitor which warn's you or rattlesnakes on the trail....
