A nice highway trip of approximately 120 miles.

Starting at Harley Davidson of Seattle go north on Evergreen Way and take a cross street east to I-5.
Proceed north along I-5 to Hwy 20 at Burlington.
Take Hwy 20 west till you get to Hwy 536 and turn south. Follow the signs to La Conner, near Shelter Bay.
Avoid confusion and follow your steps in reverse to get home again. Some of these country roads look alike.
