Licenses are a huge deal here. You need one for each State. My restricted license is $15, I have to add to it to fish for salmon and trout. Out of State are real expensive, and my Canadian license is $78, plus their "sportsman card" which costs more money, but is good for a few years. I spend big money on licenses, but all of it goes back to the States for the DNR, and MNR in Canada.
I got busted ice fishing once, in a place you have to take a boat to get to the ice, and was 100 ft inside Canadian waters. The guy actually pulled out a GPS and showed me the line of their waters when I told him he was in the wrong country to give me a ticket. He was cool, didn't take my perch, which I kept pulling in as he and I talked LOL. He could have taken everything, all my gear, which is worth many thousands of dollars, we're very serious about hard and warm water fishing.
The ticket was $150, and I had to buy their license too. Expensive mistake, won't do that again. It was innocent, I thought I was in the US.
