One thing, take the Yellowhead 5 from Hope to Kamloops and cut across to #1 or even take 5 all the way to Little Fort and take #20 across to #1. 5 is 4 lanes with very little traffic all the way to Kamploops but #1 is mostly 2 lanes with more traffic. And they don't call #20 the Fishing Highway for nothing. Kamloops is the last city you'll pass through with every major store chain and convenience till you get to Anchorage, although Williams Lake has quite a bit. I drive #5 several times each summer on the way to fishing...geez lots of years I don't even buy a WA license any more.
