That wasn't directed at you - that was sarcasm directed at anyone from Minnesota or Chicago who might think it was a good idea to bug out in Wisconsin ;)

All joking aside, there are only a few bridge across the Mississippi that are already jam packed now (Hastings, Hudson, Still water, Taylors falls). I highly doubt they will stay open for long without completely clogging up. Some will go around way up north and around, or down south and cross at Winona, but most will not I think because of lake of gas. They will be on foot before they cross the river, and the "golden horde" won't make it too far in. I honestly think Twin Cities people will end up going North (summer) or South (winter) on the I-35 corridor, or west on either 90 or 94.

Chicago will be even tougher. I don't think many will opt for Most going north will try to go on the Northwest tollway and will get jammed up in Beloit/Janesville or if they definitely will not make it past that Madison. The back roads are much better as the small resort towns like Lake Geneva will be overrun and impassable. They might be able to swing west and go around Rockford and come up in SW Wisconsin. The roads suck there, especially if you don't know where you are going. Also, if you make it that far west, why not just go to Iowa or out west?

Milwaukee will have the same difficulty with Madison as Chicago refugees have, so you will most likely have to travel either 43 or 41. 43 will be a road to nowhere as it will get stopped up at Green Bay. 41 is the best bet, and you could either cut over to north central Wisconsin, or go to North East Wisconsin or the UP.

It looks easy on a map, until you actually make the trips and see it in person on a holiday weekend, which is the best approximation of a large scale evacuation we currently have to go by.
