The Dean Dome thing was me and a friend, my preacher actually-who is a Duke grad, drove over and toured the facility. It was several years ago and maybe things have changed, but at that time, you couldn't get down on the floor. We went to what looked like some administrative office and began to beg and plead with the lady in there to let us on the court to take a picture. Told her we were both UNC grads and just finished driving all the way from Ft. Lauderdale to get there. She finally said, "Let me go see what I can do".
She comes back and says it's okay then proceeds to take us down on an elevator to the court. We shot a few buckets with the ball we brought and took pictures. As we went back up, I asked her if Coach Smith, since he had retired, still had an office in that complex. She said, "Who do you think gave you permission to get on the court?" I looked at her and held up my camera with another hurt puppy face. She just glared and said, "Don't push your luck, you aren't getting in to see Dean Smith."
Oh well, can't hurt to ask. It was awesome as hell just setting foot on that court.
