The boundary waters are very cool. I knew little about them, so I'll regurgitate what I know, although there is probably a better description in the search link above. The boundary waters are a regulated preserve of wilderness, stretching from Northern Minnesota into Canada. It is comprised of over 1000 lakes, mostly interconnected. Regulations cover the basics: permits required to go in, with very limited numbers of entrances and entrance traffic. There are no motors permitted. And you must "leave no trace".
We had two canoes (four people, five bags (~30-60 lbs each)) and we went for three days, two nights, and about 15 miles (upstream). There were about 12 "portages": places where we had to land, and trek out bags and canoes across land rather than rapids, that ranged in length from five to eighty rods. A rod is approximately 16.5 feet. There were a lot of large flies on land (clocking out around 8pm to be relieved by mosquitos), such that morning and portage activities were minimized.
My father stepped on my glasses the second afternoon. This meant that the third day of canoeing (I'm generally in the rear of the canoe, "driving") was interesting. I saw an Impression-ist view of the wilderness. My glasses were patched back in civilization, though I'll have to get new ones soon. These now have a nice eccentric style (one of the ear bits is from a completely different style of glasses) that I kind of like... but they are not quite right and cause mild eyestrain -- and have some pretty neat scratches.
It was very nice to be 10-20 miles from the nearest source of the electric grid or car. Very quiet, except for the loons. Lots of wild life observed. A complete and total disconnect. It seems like I keep arriving in these situations when I am least overwhelmed by modern society (Vermont, etc). It is when the computers scare me that I want to run away -- and that can not be scheduled.
Perhaps, with a car and a flexible job, it will be. I could just hop in the car and hide in VT.
