According to locals I was lucky to catch a real sunset in Portland in the month of February, they said that it fairly seldom event. Mostly the sky is overcast or it is raining. Sure enough, next morning it started raining, entire Pacific North West was under big rainy storm. It is rainy in that part of the country.
Last summer we stayed for a few nights in a little lovely town of Yachats Oregon. About ten or so miles north of it is the town of Waldport. It is not a big town but it seats on the Alsea Bay and HW 101 crosses it, providing some shelter for boats and opportunity for some photography. I think we went twice to this place for sunset photos, this one was on the first night.
