So, I want to go to Trawlerfest in Anacortes in a couple of weeks and REALLY don't want to ride up I-5. Is there a website a person can go to to plan a route to download to my Garmin? This is probably a dumb question, but when I did a google search I really didn't get much help. OR, should I just plan the trip on the Garmin from way point to way point? Thanks!
