Most folks will be arriving Friday. We'll be starting a ride Saturday morning, too early for you to make it to Kerrville from Houston. I would suggest riding in Friday, if you can at all make it. We rode in late Friday night last time. Of course, we had four eyes watching out for deer the whole way, and at times I felt that wasn't enough.
If you just plain can't make it in Friday, then tell me what time you'll arrive on Saturday. I'll try to arrange something with you. Maybe meeting us at our lunch stop, or something similar.
Either way, Saturday evening tire kicking, and Sunday morning ride is open. We might have a Saturday afternoon mini-ride, but that isn't set in stone.
