We made the same trip and stops last month and camped on Lake Laberge west of Whitehorse, the lake that inspired the poem, The Cremation of Sam McGee
. Stop at the Yukon Brewery in Whitehorse. They brew and sell can beer and each can has a Robert Service poem on it. Yukon Red Amber was my favorite. We bought a limited issue print, "Moonlight Encounter" by Yukon artist, Nathalie Parenteau in Dawson City, and later learned her similar artwork graced the can and bottle of their Yukon Red. So not only are the cans graced with Robert Service poems but original artwork by different local artists.
We drove 10,500 miles total on our Alaska trip up the Alaska Highway and back down the Cassiar Highway on original Continental tires on our Sprinter WITHOUT a spare tire. Boy were we daring. The tires, btw, are pretty much shot after just 35,000 miles. I'm going to replace them with Michelins.
At the Lake Laberge government campground this German RV came rumbling in and camped next to us. They had no spare tire problem or fear of potholes.
