Where can I find old bikes frames in chicago area?

Question

Would I search a junk yard or are there places I can look elsewhere?

Answer 1

Where I live I usually go to the local scrapyard if I want spare parts etc. and I presume you have those in Chicago. Failing that I would ask my local bike shop if they have any old frames they want to get rid off.

Answer 2

Try trawling the river...
