Bob,

I am pretty confident that you are overestimating the field size of some of the NASA classes you quote and vastly underestimate the size of the IT fields across the country. IT is the single largest category SCCA has (keeping in mind it has 5 classes within)...but it certainly requires tracking.

It would be stupid to ignore NASA. They are a for-profit dictatorship that has done some things that the SCCA should takes notes on...but ask the Honda-Challenge guys what they do wrong. You will get an earful.

The bottom line is that new OR old, no matter what marque you like, IT has some real solid options for you.
