Thanks for the suggestions and the handy websites. I'm mostly looking for a route I can ride from the house and back. Right now, I'm looking at hooking up to William Cannon to Southwest Pkwy to Barton Creek, then shooting over to 360 North to ride Spicewood Springs. And I guess I'll just turn around and do it again after that.

Any pointers on that suggested route?

I looked at Mellow Johnny's for the group ride options, but from what I can tell, the Saturday route is on a relatively boring road that I've already ridden before.
