So I'm looking at relocating to Seattle. My wife is from a larger city, and she loves Seattle. I've been here my whole life, ISU grad, west des moines resident. Tough for me to do, but I think I'll enjoy it in Seattle too. I like to fly fish on vacations, enjoy the mountains, and other outdoor activities. There's a lot I'll miss, some I won't, and lord knows the traffic will be on a different scale. So I'm taking my IT skills and my wife's paralegal out of state, not enough that I like here to keep me here.
Who else moved away, what'd you find out?
I'm sure you have researched the matter, but I grew up in Washington state so I figure I would give you some good tidbits.
Seattle actually gets less precipitation than Des Moines. The difference is that virtually no precipitation comes as snow and it might take 2 days of rain to get an inch where Des Moines can get that in a hour.
Traffic in Seattle is BAD, flat out. I've never driven in Chicago, but Seattle is probably about like that. There is only one interstate going though Seattle itself and only three in King County (which contains about 2 million of the 3 million that live in the Seattle area. If you have to take I5 for any reason you better plan plenty of time.
The state has about a 8% sales tax and that is about it. No income tax and almost all new tax has to be approved by the votes. If you live near Portland, you can live in Washington and not pay income tax and shop in Oregon which doesn't have sales tax.
Public lands are plentiful in Washington. This is something I missed dearly when I was in Iowa. There is always a new waterfall to go see or lake to hike into and, depending where you go, a lot of times you will only see a couple of other people and no development.
I personally live on the east side of the Mountains and if I were you I would look into eastern Washington instead. Climate is dry with most of the precipitation coming as Snow over the winter months, but the winters are typically better than a normal Iowa winter. It's more agricultural, in fact almost all the farm land in the state including the apple orchards are on the dry side of the mountains. I personally would look at Wenatchee or Spokane. Both have a good climate and are more family based than Seattle, but are receiving a influx of IT businesses from Seattle. And instead of driving over to the east side for major holiday's like much of Seattle, you can go fishing or hiking or camping on any given day.
