I would try another Jamboree sooner than 5 years too...but the Jimboree was (IMHO) more fun than the bushwacking.  By that time we had already felt fairly "bushwacked out" by the wet weather and long portages we chose to take to get to Cairn.  A central location deep in the Quetico is nice, not many people and still makes a challenging trip to get there.  A last mile or so of untracked woods might not be necessary to have an equally good or better time for a future event.   IC
