I would recommend spending several days in Superior National Forest and Voyageurs National Park (especially if you like back country canoeing!), with a trip to the U.S. Hockey Hall of Fame in Eveleth.
:-) I suppose it is, but it was at a resort so I assumed it wasn’t the rugged north you meant. It was where I encountered a bear while running on the resort’s trails alone. Scary to my then 18 year old self-I learned to start thinking about where my running took me rather than just assuming I would be fine no matter what.
