Glad to be helpful.
Don't recall being disappointed anywhere, but I'm a small town guy. I don't expect a lot when I'm out in the wild west. I was pleasantly surprised all the way. Can't wait to do it again.
Here's the quickie trip report, if you're interested:
We headed west out of Dallas and then came down US377 from Stephenville to Junction. Then rode the super slab to US83 and then south to Leakey for the night at the Leakey Inn and dinner at Friends Grill. We went around the sisters clockwise from Leakey the next morning. 337 west from Leakey is twisty and scenic. It was misty so the scenery was spectacular. 335 north is also twisty and scenic. 41 to 336 is straight and flat. 336 is more scenic than twisty. There's a really interesting historical marker down near the southern end of 336. One of the last Indian attacks in that region. It's a good story.
The last gas was in Barksdale as I recall, but Rocksprings is not too far out of the way west on 41 if you need it. My 950 didn't. My buddy's bike has a small tank so he carried a gallon with him.
We took off for home the next day in the rain heading east on 337 to Vanderpool, Medina, and Boerne. I enjoyed this drive maybe more than the others. Very twisty as you climb up out of the Frio valley. The rain stopped just before Medina. We only had to dodge one deer. After you're out of the canyon you can cruise and enjoy the beautiful scenery. That day was a really good one. Wet and cool, but fun.
I'll probably do it the same way the next time except to spend a couple of extra days checking out the state parks, the motorcycle museum, maybe ride down to Langtry and see the Pecos canyon bridge. My buddy had to get back to work, so we didn't get to tourist around much.
