Chicago area stores?

[Burks]

I'm heading to Chicago (along the turnpike) and was looking at stopping by a few stores while I'm there.
Does anyone have a list of freshwater or marine stores in the area and along my way? Any store will do, whether it's a favorite or just one you stopped by once.
I prefer marine but hey, I have lots of fresh too!
