Gary, This was my first year at the event, but I can at least comment on what we did with the trailer/security. Trailers/tow vehicles were parked at the pool parking area (I think). It was a bit congested with mountain biker parked vehicles/other trailers when we loaded car on Saturday night, but it was doable. We unloaded my convertible friday night and left it parked outside overnight at the lodge along with at least 20 other shelbys. I wasn't worried about it since we were inside a park - perhaps I should have been, but no issues. I've been caught in the rain driving my shelby so I am getting more comfortable with leaving it outside overnight, etc. If not for my friend Vytas with an enclosed trailer and tow vehicle, I would not have attended the SAAC conventions at VIR, Poconos, Mustang 50th show in Charlotte, NC, etc. I don't know how to do the tie down process. Vytas has a lock on the hub so trailer could not be towed away very easily. I have the car, and he has the towing capabilities, so together we can trailer my shelby. It is a good team effort. Hope this helps.
