I think you're undoubtedly right about NY, Chicago etc, but the thing is, I wouldn't consider living in any of those places no matter how good the job was! So even if Seattle has them all beat, that wouldn't be a factor in my decision.
Seattle does sound like an absolutely beautiful place to live. I used to live in Minnesota, which is probably similar to Seattle in that it has lots of wilderness and forests to explore. But I moved on because it was time to focus on climbing, so what I'm really looking for in a city now is easy access to good quality rock. At the moment I've got an enormous amount of world-class climbing 15 minutes from my house! I'd sacrifice *some* of that for a job opportunity as good as the one I've seen in Seattle, but I wouldn't sacrifice a *lot* of that.
Thanks for all your input people, keep the thoughts coming!
