Look out Seattle here I come

Well not next week, but I'm thinking over the summer sometime.  I took a look at Google Earth and its about 1100 km (700 miles for you non Metric people).  I figure I can do Calgary to Spokane in one day and then have a relaxing 2nd day drive. 

I'll be honest with you I'm more than a little nervous about the trip.  I've had the old girl out 2 or 3 hours on the open road but never so far from home.  I guess you have to kick them out of the nest at some point right?  I just worry about having a break down in the backwoods of Idaho and having to depend on Cletus to get me back on the road.  Friends are telling me not to worry because everyone loves a VW bus.  I'll remember that when i am creeping up a hill at 60 kph (40mph) and i have a line of traffic behind me a mile long.  I'll just flash them a smile and a peace sign as they go whizzing by me honking their horns in appreciation of the Green Monster. 

The tentative route so far is South out of Calgary (duh) through the Crowsnest and down through Coutts/Kingsgate on to US95 to Spokane.  Over night somewhere in or around Spokane and hope I don't get killed in my sleep (thank for the mental images Kel!) then onward on Seattle.  The other option is to stay in Canada and head West on the #1 right to Abbotsford and cross at Sumas.  Either way I have to make it from one side of the rockies and back again... maybe out one way and back the other?

Any comments?  Suggestions?  Things to do and or see along the way?
