If you are North of Austin I'm thinking Leander or Cedar Park? I'm in the area and some of the best roads are in your neck of the wood. Look up Lime Creek. I'm about 10 min from there and there are always impromptu runs....stop at the Shell station (coco's) wait 10 min and guaranteed you will start meeting car club ppl. Especially on the weekends. If you want to meet up sometime let me know. I'm also doing this event with my son out a Cota if you need something do to.
