On a side note; I was working as assistant track manager yesterday for a lapping day run by some privateer club. Lambo's, ferrari's, mclaren's, the type of cars people with too much money and absolutely no sense of drivink skill or track etiquette would buy. On two separate occasions we had people stop and go reverse course. By far the most atrocious bunch of drivers I've seen on track. The day ended with some guy thinking he could brake later than his big 5.0L Mustang would let him, and ended up breaking two cement blocks and moved them a solid 4 feet from where they originally sat...
So I guess what I'm trying to say is if you ever choose to do a lapping day, make sure you pay attention at the drivers meeting and familiarize yourself with where the track goes and how the flags work.
