Well I have not been to the Austin meet ... well not exactly, last year a group of use from Houston ( three Superformances) trailer-ed our cars to Austin and planned on meeting up with the group but got sidetracked into the Texas Hill country. WOW what a cruse. I think we ended up putting 400 miles on our cars and never got close to Austin. started at Marble Falls for breakfast at the Bluebonnet Cafe and ... well I would be the worst to give directions. We also found this cool Hotel in Fredericksburg, The Hanger Hotel.
http://www.hangarhotel.com/ we checked out the rooms for a future starting spot to cruse the hill country. And the BBQ in Llano ….Coopers… !!!! I found a great article in American Drives on the Texas Hill country and all the great crusing roads. (I will try to attach but think it is too big. If you would like a scanned copy send me an email with you address and I will send it off to you). There is so much to see and drive in the area around Austin with out ever getting on a highway... never understood why the group never cursed the Hill County. sorry just my 2 cents worth
