I just got off the phone with Kaye at Roebling Road. Either M or SA helmets are acceptable as long as the date range is in line. That means 2000 or newer. Josh is correct in his observation that they aren't inspecting helmets or cars, it will be our responsibility to police ourselves. I am sure that we don't want any issues, so let's all be proactive here and get the correct equipment. And they don't have helmets available for rent at the track, so you'll have to make other arrangements.
