As I stated in another post, I think pre-sold tickets would help with alot of the problems. You can limit the amount of cars to whatever the max is, and then you don't have 2000 cars all trying to enter the lot at the same time. Most bimmer owners would not have a problem with a $40.00 advance ticket price to save spending an hour burning gas and time waiting in line. With advance ticket sales you may be able to better organize the different models as well. I like the Rose Bowl idea, but the entrance areas can be crazy if everyone shows up at the same time. Orange County fairgrounds would be nice, but very expensive. I have gone to a nice show in Ventura that had all the cars spread over what seemed about 3 acres....very nice, plus enough parking for specators.
Hope to see you all next year wherever.........
