Howdy -- I'll be in Chicago for work, which ends on a Thursday around 4pm. I've seen Chicago so I'm looking to to take a roadtrip somewhere before my flight Sunday at 7pm.

I've been to Milwaukee, open to driving around 4hours each way, but prefer less. I love transport (air, car, train) museums, hiking and general sightseeing, not a big history buff. Also will be traveling by myself. I'm 25, but not big into partying.

So what do you say locals and Chicago fans? Any tips are much welcome!

Thanks.
