I've heard ST Helens is an incredible ride. I haven't been up by ST Helens though since the mid-80's. It kinda blew back then (Sorry bad pun)
Anyway I grew up in Sunnyside and still have family in Yakima so I get up that way from time to time. Mind if I look you up next time I'm up that way? Know if anyone rents bikes in Yakima? Even if it is a Harley, at least it has two wheels.
