MK-

Stayed on 4L on Quetico Lake a couple of years ago.  It may be further north than you want to be but is beyond Eden Island.  Plus, you can shoot the gap just north (north-northwest) of there and be on top of some of the picto's very quickly.

The site on PCD is listed as a 4 and has ample tent pad space for your crew.  Caught a few walleye off the western side of the campsite (although its pretty shallow there).  Since there is only a dead-end bay to the east, there shouldn't be a lot of traffic passing directly in front of you.
