Chicago Style Competition

[Waidmann]

Has anyone here every heard of "Chicago Style" competition? Reason I'm asking is that a buddy and I are running our first every "Five Spot League" at our club. We had a woman show up the first week with a recurve claiming she and her husband has previously shot Chicago Style leagues or competitions. I've never heard of that, and a google search under "Chicago Style" only got hits on a writing style. Nothing about archery.

So...anyone?
