So my cousin and I (21 and 19) are flying to LA and road tripping up the coast and departing from Seattle. We're going from May 25th to June 5th. We plan on going up the coast to experience the landscape and beautiful features. We're not much into attractions. We plan on more of a scenic drive and experiencing the sights. We're very adventurous and pretty much down for anything. Any tips or even must see locations we should stop at in Washington? Feel free to ask any more questions. Thanks for the help!
