Hi Matt - got your PM on this.
Although a bit of a slog from the Carolinas, it is well worth it. Sebring is a great indicator on what to expect at Le Mans - and is probably THE American classic enduro.
The party atmosphere (now billed as a Spring Break destination, so lots of flange) is great and the weather is usually very agreeable.
Fax, Dave H and I usually meet in Orlando on the Friday and drive down to the circuit early on saturday morning. For the past couple of years, we have met up with Smokie, Chris, Canada Phil and Pigeon, for breakfast beers and a bit of a gossip.
I'd recommend it and look forward to seeing you there, if you can make it - By all means join us in O'town on the Friday, if you'd care to - we tend to get a few practice beers in, to steel ourselves for the day ahead.
