I just returned from my 9 day canoe trip in the Quetico Wilderness of Ontario.  113 miles of paddling and portaging.  OOF DAH!!!     This trip was very difficult for me, and I think that it may well be my last one.  I am in good shape and did about as much prep as possible, but the years are catching up to me.   I did hang in there with two fit 49 year old advisors, and 6 teenagers, and have outlasted my old canoeing buddies by 20 plus years.     We covered over 25 different lakes and 29 portages.  The longest portage was a mile long, but the toughest was short, boggy, rocky, steep, slippery, buggy nightmare.......and to think that we did it for fun.
