Minneapolis Bike Trails

I cycled through Minneapolis and Portland just outside, and I ran across Milwaukee. I also heard that Philadelphia and Pittsburgh have trails Nice, though I've never been to one or the other.

There is a very nice trail that runs from Pittsburgh to Washington DC, I was on a good part of it. Check out this site, you must register to view the maps, but it's free and for a good cause.
