Get your maps out!! Don't really have a favorite entry point. Been off the Gunflint Trail, been out of Ey, take a look at how many permits per day allowed and how many rods to portage from parking to actual put in. Depending upon location less folks with less permits and the further one has to portage to the lake. Summer is generally busy, economy and gas price excepted. Some folks like an easy start, some like to hoof it in to "get away from the crowds" and remember the end of the trip, that walk out might be longer and hard than you want it to be.
Was up in Ely last May to pick up a new canoe and did a day trip in the wind, rain, sun, a little sleat and snow too, if I remember right. May take my son on his first wilderness overnight this coming summer. Been in the canoe since before birth and plenty of time at grandma's cabin and tent camping. Should be a fun time!
