Trois is right. I did a 4 day 4 night boundary water float when I was about 15. It was an unbelievable experience. They give you a map, food, and the neccesities and set you on your way. Your number one piece of equipment is that map, because without it there is no hope of find your way to your pickup spot. The fishing was great. Walleye, Northerns, and some smallmouth. This was the first time I ever got to see Northerns, so I was amazed at how they'll smash topwater.
I really want to go back someday. It was truly a trip of a lifetime if you like to camp.
