Mike,
I suspect my little off at Lime Rock in April got the attention of PCA National. I bet they review all accidents for opportunities to improve safety. PCA does run good HPDEs. They never said anything, but when I tried to register for a NNJR PCA event in August, I was told their insurance did not cover open wheel cars. Being a stand up kind of guy, I checked with the local regions for other events I had already registered for to make sure I was OK. Neither Metro PCA or Riesentoter (Philly) had herd of the "insurance" issue. But when they checked with National, they were told I was not covered.
I think they lumped the Caterham in with Open Wheel cars for liability reasons. Another case of lawyers ruling the world through fear of litigation.
All the people I met at about a dozen PCA events were great, no issues at all. Not every instructor was comfortable in an open car, but that extended to Porsche Boxters as well.
Anyway, it's moved me one step closer to breaking down and joining Tom and Croc at NJMP...
