Hey guys. I am heading to Oshkosh this year in my Champ and I've got a question for anyone who flies the VFR lakeshore corridor through Chicago.

My my champ does not have an electrical system. Therefore, according to FAR 91.215(b)(3) I can go through there VFR without a transponder. Have any of you done this though? My concern is that even though I know it's legal, the guy in the tracon may not remember that and stir up trouble. I had a similar issue with Toledo once.

i do have a pretty good hand held radio and have no qualms about calling Chicago approach.

I am an ATP rated pilot and frequently fly into Chicago airspace but that's always in a go-fast airplane with two transponders. I need some advice from someone who's gone without any bells or whistles.

Thanks in advance.
