Our experience........after the show we stayed and moved down to the front row to watch them clean up. Indiana himself initiated a conversation with my son, posed for pictures and autographs and explained to him he should never try any of the things he just saw. But we were lucky..........he initiated.
I would ask a CM at the end of the show if it is possible to meet him for a minute just to shake hands and take a photo. He is usually out there while they fix the set, so why not ?
