utc i don't know if i agree with chicago to macon i've taken the greyhound from milwaukee to atlanta quite a few times and there is literally nothing between chicagoland and lousiville other than indianapolis is by far the most boring stretch of interstate i've ever been on you might be able to argue for lousiville to macon if you were willing to accept places like murfresboro tennessee as a metro area i suppose you could include the fox valley since there's only a slight hiccup between milwaukee and oshkosh and that'll definetly change if interstate happens but then you risk changing the name of the region to a pit and i think there are regions that deserve to be called an a pit much more than the great lakes lol april
