I just posted more info about the rally in the DFW group and opened a discussion group if you still want more info. We are planning to all be there by 9AM with departure at 9:30AM. There is a liability waiver that needs to be signed and turned in. Let me know if you need anything.
We seem to get info almost daily. the basics are on this website for dfw smart car club.
I believe the rally starts at ten10 am and goes for two hours of the route and check-ins. you are welcome to make a donation but do not have to to participate in the rally. you can contact Tim or Brandon at this adress: email@example.com
I think that is all you have to do.
