Comerica Park was built in 2000, eight years before the recession started. How long of a wait do we need? Granted, not long after it opened Kwame took office and pretty much wasted all the goodwill Dennis Archer had built up with the state and surrounding area - but there are no guarantees Detroit won't elect another guy like him in the future.
I'm in favor of a new arena, but I don't see why it requires public financing. I don't believe for a minute that Ilitch would build in the suburbs. That would go against everything he's done for decades.
