Not that anyone is taking this seriously, but Rosemont would be an interesting spot for a new stadium to say the least. The entire village borders O'Hare Airport, so there would be planes taking off directly over/near the field constantly. The village is tiny and pretty much consists of their entertainment district with the Casino, Convention Center, convention/airport hotels, Allstate Arena and retail. I think the entire population of Rosemont is like 4,000. I'm assuming this "prime piece of real estate" would be right in the heart of this. The town borders Chicago to the east (and west since O'Hare is technically part of the city), and is about 10 miles west/northwest of Wrigley Field/Lakeview. Anyways, not gonna happen but I'm glad there is at least one ambitious mayor throwing this out there just to raise the stakes ever so slightly. Edit: Also, I'm not sure if Rosemont would be willing to put any money into this field...probably but I don't think he said anything of the sort. If they were to build a brand new stadium and everything else, there's gotta be a lot more involved than the $300m the Ricketts are putting up.
