I will vote for SEATTLE
!!! I LOVE IT HERE!!!!!!!!!!!! Jobs, Truely glaciated mountains, lots of great hiking and climbing folks. Great community for mountaineers. That is why REI, Eddie Bauer, and so many other climbing outfitters have roots here. You need three lifetimes to truly experience the beauty nearby.
Boston....incredible NFL team, just being that close to Brady and Belichick would make me feel all warm and fuzzy inside, super running town, love running the marathon or along the river....but same as above....closest crag has tons of mosquitoes....more than I have seen in Alaska...good luck driving out of the city to get to the countryside/trails/mts
Don't totally bash the northern Boston area or southern New Hampshire. I got heavily seduce to Seattle by Rainier and the Cascades but Manchester, New Hampshire was a good place to live for five years. 45 minutes to the ocean, and the Boston area, an hour and a quarter from the Whites, and 2 hours from the Greens, not to mention Rock Rimmon a 150 granite wall with a 5.12 on it INSIDE THE CITY. Personally I am glad I lived there but like Seattle much much more.
I was born in the D.C. metro area and lived there (except for Frostburg State University in western Maryland) for 23 years. Honestly though my parents and brother live there and I am close to them I don't go back to visit. There is some nature and the season of fall can be pretty in West Virginia and western Maryland. That being said it is no where near as plentiful as where you presently live in Seattle. You would get homesick in a hurry, especially when the humid weather and haze starts to roll in. Restaurants and culture in D.C. are great and amusement parks are plentiful (Six Flags America, Kings Dominion) (Seattle is lacking there) but that is not enough for me to ever want to go back outside of a ten year family reunion.
