I don't know how long they will be at MGM, but I was the original poster with the pictures....
The experience was amazing, as the cars drove up in front of the hat and parked, and then people were allowed to wander around, checking out the cars, taking pictures...the sounds and the detail was AMAZING!!! If I wasn't already going to be seeing the movie, this would have swayed my opinion.
Hope they continue to have this for a while, its a fun thing to be a part of...if you have any questions, let me know, I'll try to help...
