Well, I'm here on the Alaska mainland finally - I don't count my 2 hr excursion to Hyder as making it to Alaska.
The Alaska Highway, west of Destruction Bay till the AK border is a REAL ROLLERCOASTER of a road way. It appears repairs have not yet begun, except the last 10 miles east from the border, they had the pilot car and traffic control setup, but no repairs underway yet.
Despite driving mostly around 30-40kmh, I lost a trailer tire about 90K from Beaver Creek. Nothing much to swapping it with the spare, I was ready with a 24-inch 1/2" drive breaker bar and an cordless impact gun. As I was gathering my tools, three long 5th wheel rigs blew by me at 80K, so I setup some flares about 200 meters up the road from me. No other west bound traffic after those three trucks, go figure.
As I had finished installing the spare Yukon Highway Assistance showed up, KUDOS to them and whomever alerted them to my break down. I had the tire swapped in about 20 mins, and was happily surprised they showed up so quickly.
For my last night in Canada, I illegally parked on the North side turn out of Kluane Lake for the night - WHAT A VIEW! I understand and agree with the NO CAMPING signs, but there's also new looking NO OVERNIGHT PARKING signs at every single turn-out, pull-off, rest area, boat launch, trail head, etc, only in YK, and nearly every gravel pit has a shiny new gate across it. In BC, the rest area signs read please limit your overnight stay to 8 hours, and I don't recall any signs at the pull-offs.
