Just wondering... I thought that coyotes had an open season 365 days a year in the past. I check the last 4 or 5 years and it seems that it has always been October 15, 2016 – March 15, 2017

Was it ever 365 days per year?

I checked Illinois and it is Year round (Statewide) minus a few deer hunting days.
