Unfortunately not many details concerning LOG have been posted.
Besides the already announced Friday night reception, Saturday's formal banquet and Sunday's less formal banquet, people's choice car show, judged car show, auto-x, scenic drives, gimmick rally and the arts & crafts exhibit. I know of the following.
Satch Carlson longtime Lotus lover and comic car writer will be the Saturday evening speaker. Bob Dance, long time Team Lotus mechanic and Ken Szymanski Lotus F1 tire change (his is an amazing story http://www.nytimes.com/1987/06/15/sports/auto-racing-east-side-resident-helps-lotus-team.html) should be there.
The Barber Vintage Motorsports Museum will have a presence although I don't know exactly what will be exhibiting.
Lotus Cars USA will be there.
The Lotus factory seems to be cooking up something. They have given hints but have not said anything firm as yet. I'm hoping that they will bring the Evora GT4 and the T127 but that is just my wishful thinking and not anything more that that.
I believe there will be technical sessions for the very early cars (e.g., MK6, XI...) Elans, and the Elise/Exige. I think I heard of a detailing session but I may be wrong. I was getting desert when this was covered.
There is likely to be some authors doing book signings. Actually it seems like the place will be crawling with various editors, authors and publishers.
There will be a car wash area and informal slot car racing.
A few specialty vendors will be there as well as having a low key swap meet.
A confirmation letter will be sent to all registrants.
A lot of people will be showing up on Thursday including 20 or so LOG volunteers.
