That's a nice find. I camp in Prince Albert National Park every fall once the summer camping season is done. It's very peaceful. That rail portage is well maintained. We went for a hike down that portage in 2014 and made it 50 meters from the put in at the north end when a bear walked out of the trees and headed away down the trail. I felt no shame in turning back. The banner on my Youtube page is a view about a half kilometer from that portage on the Grey Owl trail. I agree about the switch paddling, but it did look graceful. Thanks for the link!
