Totally agree. You see the sights in the first hour, spend the rest of the day driving around in circles, and then wind up back where you started without actually getting anywhere. OHV parks are great to practice your offroad driving skills but unless you're super into just running trails without any actual destination, they get old fast. If you're on Facebook, there's the Texas Overland group and they have a bunch of back road routes in the Files section. Except for the OHV parks, the best you're going to find here in Texas is county and forestry roads - really nothing like what you see in New Mexico and westward.
