Re: Alaska
Thomas - The Boss Lady and I drove up this Spring. Left Florida on May 1st, arrived in Anchorage on May 26th. Would have been there sooner, but spent four days in North Florida with our niece while our generator was being looked at.
The campgrounds in Canada all seem to open around May 1st, so we didn't have any problems finding a place to stay. Gas prices thru Canada were HORRID!!
They sell gas by the liter and the most I paid worked out to $5.45 (US) per gallon. I planned our trip for 300 to 400 miles a day, and gassed up whenever I got to half a tank. I towed our Chevy van on a tow dolly but had no problems finding pull-thru camping spots.
Expect the roads to be suffering from "break-up" in the Spring. The roads frost heave during Winter and the pavement breaks up. The Canadians are very good at marking the broken places. Just be on the look-out for red flags along the shoulder of the road. They had all the broken places fixed when we came back in September, except for a 50 mile stretch of mud/gravel that they were repaving.
If you go up in the early Spring you should see plenty of wildlife along the highway. We saw black bear. brown bear, moose, caribou, a coyote, a fox and a bunch of bison. Be sure to have your camera ready.
It is a beautiful trip and we will be heading out again this Spring, on or about April 15th. we're going up to PA to visit an old Army Buddy, then across to Shelby, Montana, then up into Canada and the ALCAN. I'll be checking the RVUSA website regularly (if the campgrounds or McDonald's have wi-fi). Drop me a note if you decide to come and maybe we can meet out on the road somewhere.
