You mentioned it was the only full-sized theater in your state. Out of curiosity, what state are you in? There's a list of all imax theaters (both film and digital) here:
Arizona. The Arizona Mills has an 8-story screen while the Science Center is 5-stories and the Grand Canyon's is six.
It's interesting that that list still only lists the Mills as having 1570 when I know they also now do digital.
