I personally like the Interurban Trail going north. There is some art along the way, that's fun to look at while riding--some of the art could turn into "animation" if you ride by fast enough. Some day I'll take the time to ride to Everett and back.
Problem is, it's a trail, then, not a trail and jags over to a trail again, etc. And, I don't know the street names well enough to map it out on veloroutes.org. Maybe there's a linky for it somewhere (I'll look and edit this post if I find it.)
