I agree with thirsty. The bike handling situation at Kelowna is very iffy. I have overheard announcements at IMC the day after the race stating that your bike may not make it onto your flight. And, Canadian customs once lost my bike for 3 @#(!) days! (different race)
Drive the North Cascades Highway (about 1 hour north of Seattle off of I-5), enjoy the scenery and stop in my new hometown/training mecca of Winthrop on the way.
