I got a dui in 91. and alot of this is true. I can give you 1 bad story that happened to my buddy that got one a couple months before me.
We camp in the 1000 islands every year and one morning my buddy took his wife, kids and mom and grandma in the boat over to canada to get some muffins. He docked and went to the bakery which was right on the river. Well he never called in and when they got back to the boat the canadian border patrol was there. They were pissed he didn't call in but they were just going to let them go with a warning right after they ran his ID. OOPS. Spread them, searched him and cuffed him and into the back seat he went right in front of everyone. They eventually let him out and he is banned from ever going to canada now.
So, take your chances and go thru. I would drive seperate with another guy and tell them you are going to a casino or something other than hunting. Or pay the $200 and see if they will allow you up there. Its all about money so that would probably work.
Good luck
