In Ohio, if you are caught fishing without a license, they can confiscate anything you have that facilitated your violation. Your tackle, your boat, your vehicle that got you there. That would include your bike. Many times I've had a Warden walk up to me and ask to see my licence. Many of those times, I was fishing where I never expected a warden to be, like on a river that ran along the back of a an old graveyard.

So watch out for the Buckeye Fishing Cops.
It's the same way in Arkansas no license you better not be fishing.I don't have the time to fish while I am touring to much fun doing other things.
