There is a specific subforum for Track & Technique. Lots of good info there.
Track and Technique - LotusTalk - The Lotus Cars Community
Here is a link to a local Lotus owner group page, which will be good for you to have:
Carolina Car Clubs - Index
And finally a link to track events in the Southeast when you're ready to take the plunge:
TrackSchedule.com - Coco's Drivers Ed Calendar for 2008
Good luck!
