Generally the gates open @ 7:00am

tech between 9am-10am
first runs begin 10am-11:30am
BMW CCA are a well organized group, be sure to bring a snell approved helmet if you have it (they do have rentals sometimes, but they are pretty nasty), not sure the cost for this season but it was $45 for non-members to run last season. Bring those steeds fellas, we need more American Iron out there.
