Thanks for the tip. I just read the DuFresne book.  I have only been to Isle Royale once, backpacking many years ago.  A couple questions for those of you who have paddled there.

I really enjoy the wildness of the Quetico & BWCA and so was kind of disappointed to read that at Isle Royale the paddle campsites are group sites with markers and picnic tables, portages have signs, motor boats are allowed, etc.  Can you give me sense of whether you still get a wilderness paddling feeling there?  

The book describes one end as much more heavily used than the other.  I wonder how much one should consider this in deciding where to go.   i.e., if someone enjoys a bit of solitude, would you advise not going to the "busy" end in July and August?
