Oops. Looks like I forgot about checking this post. Coolhand, I have a long dirt rd next to my house, and I just go. I string together as many dirt rds as I can find in a general direction, if I see something new, I go for it. Road numbers and names...? Pettytown Rd is good, there are a lot of dirt rds between Lockhart, Dale, High Grove, Shiloh, ...
Sand Hills Rd behind Red Rock is fun- but all forks dead end. The terrain is neat.
Sorry, they are mostly in my punkin' head.
Guadalupe and Gonzales counties have a lot of dirt rds too. There is a one lane wood/metal bridge over the San Marcos River down there.
With Toll 130 coming, things are are going to change, and not better for dirt rds. Caldwell co rd 218 has the only gravel stream crossing I have seen around here that is wet all the time. Even in this last drought. Short rd, but its close to my place, and baptizing my tires makes me smile. As long as that !bull! stays behind the fence.
I'm trying to get a friend of mine to do a day trip out here with me soon- company would be welcome.
