I ran into the GM at GWP a few weeks ago, ask me how fishing went, he was in his truck & I was on the ramp. Said the was the local warden for the area and seemed like a nice young man. I saw him check several registrations on jet skies while I was talking to him. He gave me his card and said to call him if I saw something that didn't look right.
That was the only time I have ever been checked. Had the park ranger in Kirkwood tell me on time when I was fishing at night that the park was closed. I explained to him there were no signs saying such, after about a 10 minute conversation he said I could continue fishing if I want. The only thing that night that was biting was the misqueoties so I was ready to go anyway.
