Looks amazing. I've driven the Alcan several times in the mid 2000's when I was stationed in Alaska, never camped, and never for pure pleasure (I was moving, or preping for moving) but still, some of my favorite drives and one I can't wait to do again and share with my wife and friends.
My biggest dilemma is trying to decide on when to go ie time of year, I've driven it in February, March, May, October and November... and I honestly loved February and March most... but of course camping is a no go (my hard core days are long behind me) so leaning towards early fall (to escape the mosquitos and RV's lol)
But also how to see all I want in the time I can... the distance is so vast it's hard to realize for some folks!
