Really, put it into the old courthouse at rose and Michigan. They own that too, don't they? I'm really hoping for an out-of-the box proposal for the old courthouse, preserving most of the exterior, building a 20-30 story hotel + residences out the top—closer to the arena than the gibson site.
If you thought the bike lanes were controversial, wait for anything to happen next to Bronson Park, unless it's a bulldozed building for a low-density playground.
