...and if your home state doesn't require canoe registration, MN no longer requires that you register your canoe with them to paddle within the state.

How much scrutiny do rangers give you? It's a state issue, not a federal issue. I've never been checked while in the BW. I figure if you camp is in good order and you have the proper permits, that's all they are concerned about. Does the DNR patrol for canoe registration and fishing licenses?
We've been checked once by DNR. It was on the creek between the EP1 entry point and Kawishiwi lodge. They were checking for registration, fishing licenses, and PFDs. Our brief chat lasted about 30 seconds because they could see our registration tags and PFDs and believed us when we said we didn't fish. The lack of any fishing poles probably helped with that.
We were checked last year by the MN DNR. I'm from Indiana (unfortunately) and they asked if it was my canoe and if my state requires registration, which it does not. Very nice guys.
