> Chicago is also on its last legs.<
Wait, are you looking at different figures than I am? Chicago, which last week grossed $650K, at 70% of its gross potential and with an average ticket price of $82 in year 19 of its run? With that show's low running cost, I'd venture to guess that they had a profit of $300-$350K last week. It's so economical to run, it may never close, and certainly not while it is still performing profitably.
Begin at the beginning and go on till you come to the end: then stop.
