Thanks Stu for putting in a good word! My club (LLSE) is playing a minor hand in organising this one. You are correct about the Barber Museum, and by the time LOG 37 rolls around they should have the new expansion open which will bring the displayed bikes to about 1200. I've had a VIP-tour of the museum, led by an employee who is big in Lotus-enthusiast circles in the southeast, and I got to see the 'secret underground vaults' where the bikes waiting for display in the expansion are kept. I also got to see a Lotus resto-project that they were working on close-up in the shop.
The Vintage Days event at the museum in October is truly great for the motorbike crowd, or anybody who enjoys gearhead stuff really. The NASA museum up in Huntsville is very much worth seeing while you're down at LOG too, as it is NASA's largest museum and is located there because Huntsville is where NASA does most of its R&D. Those of you passing through Nashville should also check out the Lane Motor Museum. I haven't been there yet but some friends and I are scheming to go up for a weekend on our motorbikes. If you make it down to the Gulf coast in your travels, the USS Alabama in Mobile Bay is worth a stop, as is the US Naval Aviation museum in Pensacola. Also if you're into ghosts, the southeast is supposedly the most haunted part of USA and there is no shortage of information about that, probably a few tours you can take too.
Southern Appalachia has some EXCELLENT twisty roads too! Starting about an hour north of Atlanta, the hills and curves stretch all the way to Maine. There is also a brand-new track and visitor-centre at Porsche's new US HQ right by Atlanta's airport. The southeast also has a great list of craft breweries if you're into that.
Sorry to get on a ramble; I do think that those who make the trip will be in for good stuff!
