RE: Seattle to Banff
Highway from Radium to Highway 1 junction is rough with lots of frost heaving. a pretty drive though
Best to go thru Fernie and Crownest Pass, then up Hwy 22 (the old cowboy trail) to Calgary
or thru Fort Macleod (National Historic Park) and the buffalo jump
If in Calgary the first two weeks of July take in the Stampede.
Calgary to Banff is 4 lane divided
