I live about 15 minutes away from it, although I haven't been in a while. What I do remember was the Paul Pierce tribute area which was awesome. Everything you could ever want to know about him.
There's a lot of cool areas too, they have a booth to see how your vertical jump compares to MJ and stuff like that. I had an absolute blast last time I went there. Although, a lot of the attractions were aimed at children, there was a ton of info in the exibits. I'm sure a lot has changed though.
