In the planning stages of a early June 2014 vacation. Trip will be 10-14 days...still working on details. Trying to decide on this Seattle through Canada, then Montana ending in Portland is the best itinerary. Also considering, a Canada only with Vancouver to the Rockies, or considering adding the Seattle not the Oregon piece? Then wondering if throwing the Glacier Park is worth the additional drive and if so what is there along the way to see or do from Calgary to GNP or GNP to Portland? Thank you for any advice!
