I'm in on the Kerrville Trip. There's a motel (best western or something) on 16 just the other side of I-10 that I've stayed at a couple of times. There also happens to be a dive bar next door



.
The nice thing about motels is that you can park the bikes right outside your door. I usually tie me and my friend's bike together with a 30' steel cable for security.
The ride from Kerrville to Medina is fan-freakin-tastic. Then the 3 sisters, WHEW! Then the museum, WHEW! It will be perfect!
