Here are some things I won't miss about Seattle (in no particular order)
Crack - and the people who make, market and use it.
Public Transportation. Smelly, stifling, seats too small, trips too long.
10% sales tax.
Trying to find parking.
Population density--the feeling of being crowded, oppressed, hemmed in.
The dark side of Anonymity: the feeling you're completely on your own, and God help you.
Earthquakes and the possibility of earthquakes, volcanoes, mudslides, tsunamis and other natural catastrophes.
The proximity to the Asian ports and the nasty flu bugs that disembark here.
The feeling that everything is always constantly changing all the time.
How you have to fly in order to go anywhere else in the country.
How expensive it has become to live here.
I used to love Seattle, but my love affair has ended. I have 8-10 months left before I leave, and that's going to be a long haul. I'm trying to get prepared by eliminating the clutter now.
