MY dad and I are in the early stages of planning a trip to the boundary waters this fall. Apparently you have to apply for a permit, ie know access/entrance points, early on. I was wondering for those of you that know the area, are there any suggested routes or portages to avoid for an old guy with not so great knees???? We are wanting to go into Quetico, and are looking to canoe/camp 5 nights. Thanks in advance!
