Seattle is pretty nice, especially if you can ignore the random junkies and homeless tent and RV encampments around town.
Oh no, the last time I visited Seattle was in 2010. Has it gone to shit since then?
I might be jaded but this sort've depends on your point of view. I grew up in San Diego, would weekend with friends in LA, and I've got family across the country. Most large cities that don't have overly deadly weather seem to have a visible homeless population.
