Crow are legal in Ohio year round, but only on Friday, Saturday & Sunday. We have a lot that hang out in the fields around our place. It' s kind of like hunting small turkeys. I believe coyote & wild boar are also legal year round. I' ve heard coyote but have never seen any. And good luck finding any wild boar. Another thought would be bowfishing. There are a lot of lakes around here with way too many carp. Not sure of the regulations though. Check out the Ohio DNR website.

This could be a fun thing to do occasionally but I think that 3d or just plain old target shooting is better practice to keep in shape during the off season.
