Mark Cuban and some wallstreet types are planning a new FALL football league (called the "United Football League" to play on Thursday and Friday nights in the Fall. They are targeting big cities w/out NFL teams (Think Las Vegas, Mexico City, Columbus, Orlando, San Antonio, etc.)
Check them out at their new temporary site: UFL Site
You can even get involved in helping bring a team to your city.
Columbus would be perfect --Crew Stadium is nice and is small enough to create a cozy atmosphere and make tickets a little tougher to get.
