Welcome to the sort-of Lotus family! I'd highly recommend joining Lotus Ltd and checking for a local club, if you haven't already. There's a bunch of Caterhams in our local club, in fact the president is a Caterham dealer. You'll probably find plenty of other Sevens, Caterhams, some some Berkins, etc. One local guy built himself a "Locost" in his basement, bending all the tubing himself, and installing a motorcycle engine and transmission.
In October 2012, I combined trips to Disney and Universal with the annual Lotus Owners Gathering, which was held that year in Orlando. I've got some pics here:

I did my first track day on that trip, too, down at Sebring. Huge amounts of fun!
I've got my Elan torn into bits at the moment, completely rewiring it, redoing the dash, replacing a leaky water pump, fixing a crunchy second gear syncho, new tires, new battery, etc, etc... that is doing a good job of preventing me from spending on money on camera gear!
