Traffic like that would be a deal breaker for me, though.
I'm way too familiar with 1 hour 5 mile rides. It's much of the reason I search for my escape.
I came up through Dripping Springs & Bee Cave, cute li'l towns which aren't too far from the lake. I'm just not sure what level of services/shopping/dining you'd look to do. If you needed more than a little of that stuff, you'd likely have to go to the Austin suburbs, and the traffic seemed to me to increase pretty damned fast.
