My problem with the RMRs is that they're harder to find the "Roadster" in them than in the front-engined MRs. But the rules is da rules. Might as well do the best to take advantage of them.
Still hoping for a C/AIR class in the MRs so Rich could run his Packard (but, then again, I don't think he still has it).
Years ago, as I remember, he was looking for someone to partner with to run it again. I shudda called, although I was prepared for a turn-down, knowing my history.
