The last thing I want anywhere near Seattle is a car lol...
I've been up that way for business a few times, and traffic is flat out insane. The growth of Microsoft and Amazon (and then all the tech stuff that sprung up around it), has made it ridiculous. Boeing was always big, but not "explosive growth" big.
Staying downtown and paying a ridiculous amount to park, and then not wanting to get in the car to go anywhere because of traffic, doesn't sound fun. I'll have to figure out whether I need to take transit, rideshare, or taxi to get from the airport to downtown, but then I'm going to be happy to be car-less.
