One of the few things I regret about my great state is the relatively limited amout of public land where you can wheel. We have lots of state and national parks and preserves and all that good stuff that I love...but they CAN get upity if you stray from the beaten path (depending on the park).
Unfortunately, a vast majority of the state is privately owned, and everyone feels the need to fence off their little world and proclaim it "Mine!". (to be honest, I probably would too) Most get upity if you "explore" their property (again, to be honest I probably would too.)
So...unfortunately...compared to many other states that I read about here, Texas has a relative few public wheeling areas.
As for Jeeps, Jeepers, Jeep shops. Heck we have a bundle of em. And you are gonna be in the the big fat middle of Jeep country. Take 190 to the west out of the Fort. Through Copperas Cove towards Lampasas and you will pass a half dozen Jeep outfitters, etc. That 2657 south from 190 (just west of Coperas Cove) and there is another Jeep shop just south of "Christensons Store...mmm good burgers) at the intersection of 2808.
Its a pretty drive. Watch out for Deer. Be mindful of the speed limits. (Grin)
We do like to have fun around here, but we arent nearly as "redneck" as most TV shows like to characterize....or I guess a more appropriate term would be caricature-ize.
Welcome to the neighborhood.
