hmmmmmmm, interesting question. wish i knew the answer to that. i think for the bulls and/or blackhawks in chicago (both in playoff status as we speak) the stadium floor is set up to “switch out” for wood or ice floor based on sophisticated technology that allows your thought in question. how they do it, i am not sure. but i do know, at the united center in chicago (the home of michael jordan), both hockey, disney on ice and basketball are all played played interchangeably in the same season in the sane arena.
