Preliminary inquiries show my itinerary, which was to include a ship to Alaska from a west coast port, plus railfanning in Alaska, plus return to Vancouver, is going to break the bank.
So now, I'm thinking of ending my westbound train travel in Vancouver, revisiting Vancouver for awhile, and seeking a backpacking opportunity not too awfully far from Vancouver. Preferably four days/three nights on a circuit, likely involving a shuttle or rental car to get to/from trailheads. I will ask the same questions on hiker-related sites/FB groups I participate with, but if by chance anyone here has suggestions I'm all ears, er, eyes.
At the conclusion, I'd return to Vancouver to catch the next day's #2 back to Toronto.
