I lived in Mpls for about 28 years, recently moved to Seattle and don't regret it. It doesn't mean I won't come back, my family is there and I love northern Minnesota (cabin country!).

The cold didn't bother me much.

Things that bother me on the coast are the insane traffic, the seemingly lack of aid and/or housing for large homeless populations, yes the high cost of living. But it's mostly awesome.

I'm missing a lot of useful points here, just some ad-hoc thoughts.
