This happened before to St. Louis
The Football Cardnials wanted a new stadium, we told them to take a hike to Phoenix Az. Our economy didn't suffer, and eventually the RAMs moved here and did a much better job of winning games than the Football Cardinals did.
But what if we build this stadium, and they decide to move?
Remember when the Football and Baseball Cardinals shared the same stadium? Now each team has their own stadium.
It hasn't been the same since the "Old Barn" aka The Arena or Checkerdome got torn down to build business buildings. All it needed was some foundation work and remodeling. But noooooooo, corp greed once again gets control and they build a new hockey arena somewhere else and tear down the old one.
I am free now, to choose my own destiny.
