This is what Detroit calls “state of the art” in convention centers. Some Brady Bunch designed thing from the early sixties, that looks like it hasn’t seen a building inspector since Lyndon Johnson was president.
Example: the Cobo Convention Arena.
Counselwoman Monica ‘mad dog’ Conyers actually insinuated that somebody went on top of Cobo and drilled holes in the roof just to make City Counsel look bad. . . yeah.
But twenty seconds of inspection shows serious structural issues everywhere you look.
