The 2 times I have been, they have been very lax on the HPDE thing.
They asked for a show of hads at the beginning during the "meeting" of those that "have never driven on a closed course before." I found this question odd becasue of the HPDE requirement. It contradicted with their web site. About 10 people rasied their hands.
They then offered (not required) to put a driving instructor in the car with each of those people for the first few laps to get them comfortable. They then turned them loose for the day. I thought that was very cool of them.
This is a VERY LAID BACK environment guys & gals that is just about having fun on a real race track in a non-competative setting.
