i did a route similar to the one marinomi described this summer on my drz. in 7 days you'd have enough time to get to banff and jasper and double back thru revelstoke and kamloops. if you where to go thru pemberton, i recommend taking the road north to d'arcy. its not a long road, but its alot of fun!
destination highways is a good book. the only thing i have to say negative about it is it is definitely catered to sportstourers and bigger capacity bikes. my 400 supermoto liked alot of their secondary roads much better
what time of the year are you planning to ride? what kind of bike will you be riding? do you want to stay in bc/alberta or do you want to go south into the states?
