Did you ever visit the Pontiac Silverdome? I did, circa 1984. It was surrounded by a 1/4 mile wide strip of parking lots, and beyond that just more dirty, rundown warehouses and light-industrial buildings. Surely not the "entertainment mecca" the lying politicians and Ford family owners probably promoted it as.
If the movers and shakers of NW Indiana want a 'kickstart' let them pay for it with 100% private investments, and leave the public out of it.
