Oh yeah, you should check out the Museum of Science and Industry. They have a U-Boat exhibition there. Lots of cool stuff! :D

Sounds interesting! Hopefully it's still there when we go!

The museum was pretty good. Not a big history fan but I wasn't bored. Make sure you bring a camera with you though. :)

Here are some pictures I took when I was there:

^ Millennium Park in Downtown.

I'm not from the Chi but I would definitely recommend going to Wrigley Field and seeing a Cubs game.

Wrigley is one of the most legendary sites in baseball
