Something else to seriously consider, having just put on the track event...It seems like every year we get less NSX owners interested in tracking their cars. I don't know why, but it's become a very difficult sell which has required that we open it up to other marques in order to break even. Even so, we struggle to do so.
This year, HPR being my home track, I know quite a few drivers from other local clubs (PCA, CECA, etc.) and expected to be able to easily fill our numbers; but the Monday/Tuesday format worked against us in a serious way! The thing about locals is they get to drive this track (wherever it is) all the time, so it's not worth taking extra time off work to do so at NSXpo and that hurt us this year. This becomes even more important the more expensive the track is to rent, as will be the case with either VIR or RA.
Without an abundance of local NSX owners near the venue with obvious motivation to attend (and I mean a whole lot, a la California), I would seriously consider holding it on the weekend to boost local participation, perhaps concurrently with some of the less interesting social events to reduce the temptation for NSX owners to "go social" instead.
The other thing to consider is only doing a one-day school but I've had several people tell me they'd have no interest in cutting the time down.
