We will be in Houston at the end of October for the International Quilt Festival. I have no classes on Wed. so we are thinking about a day trip to Austin and perhaps one of the Hill Country Scenic Drives. (My husband likes to drive and when we lived in Monterey CA we often drove to San Francisco for dinner). Would we be crazy to leave Houston between 6 and 7 (Traffic?), to get to a campground in Austin in time to sleep? I was thinking about McKinney Falls State Park. We'd spend the day in/around Austin, returning to Houston Wed evening? What would you recommend for our day in Austin? We aren't really city people....that's why I wondered about the Scenic Drives. What's your favorite? Thanks.
