Never heard of it, but kevmarv puts on the Killington Classic which seems to be successful. However, I’ve never went over there for it so I can’t offer any personal knowledge.
I've gone to these for the past 4-5 years. Not really worth it. Just a bunch of tshirt and patch vendors. The venue in Marlborough is very small and just a few bikes are out. But its the only thing going on in New England.
