The Plans are for a DOME and not retractable, I know you are very smart man, so understand that the Chicago Bears are not building this stadium to be used for only 10 Sundays a year, they want it all, Super Bowls NCAA football/Basketball/UFC/WWE and list goes on. You do not get that in Chicago land by leaving it as an open air stadium
Next thing, Kevin Warren has been on record mulitple times that the stadium itself, just the stadium will be privately funded
What he did say was they needed munciple help in Arlington, perhaps that could become a tax issue for the residents, talking roads, drainage, et al, but not stadium itself which is more than acceptable to me.
I think this is the media session from last week
