I'm not first-hand familiar with Oregon, but some parts of Washington have moderate temps. Coastal Washington gets a lot of rain but rarely freezes and -- anecdotally -- at least one city in Coastal Washington has vastly worse rates of homelessness on a per capita basis than some of the cities infamous for it, like Seattle and SF. And, yes, they are mostly camped outside, not in shelters.
Which city? I was in Spokane recently (obviously not the coastal city you are speaking about) and was surprised by how full of homeless people downtown was.
