I completed my trip from Lake Superior to York Factory this summer, and much of my crew's route paralleled Sevaried's and Port's.  May 26 - August 9.  What a trip !!  I would do it again, too, but there would be some changes.  My book will be coming out in a couple of months or so.  

If anyone has the opportunity to do this, take the opportunity.  You will have memories for the rest of your life.   :)
