Don't take a compass to Hudson Bay!
In Hudson Bay there is a gravitational anomaly that will mess up your compass. If you do the compass will spin in random directions, and it would very easy to get lost. Luckily, it can be hard to get Hudson Bay, so you probably won't go there.
Minnesota problem!
In Lake of the Woods Minnesota, the only way to get back to the rest of Minnesota, you either have to take a boat, or drive though Canada and then back into Minnesota.
