Filed KGYY Niles V7 Thorr OBK V228 KMSN.

I mostly wanted to see what Chicago would give me (curiosity) - also
the filed route would have been a little shorter and smoother than
flying around the southwest side of the Class B.

Clearance was vectors to BAE. Actual was over the lake until past
Kenosha (KENW) then pretty direct to KMSN.

I flew back VFR in half the time, though due in large part to good
winds.
