It's the start of the off season ... not all that surprising that no one is responding quickly.
But I've said it before in this thread. Money talks. Next year, when track days are announced at TMP (doesn't matter who organizes them), call the organizer before signing up and ask the right questions. Will there be sufficient hay bales protecting that wall; will the ambulance be there; etc. I'm with N3WMAN on not pre-paying - but if you go there and the hay bales are not there, no dice. Obviously, until TMP develops a consistent pattern of properly taking care of their customers, I would not expect very many people to come there from far and wide, given the issues that dricked mentioned.
