Downtown SLC is quite different in size from Seattle; you could walk the ride-free area in SLC in about 30 minutes, the ride free area in Seattle is much larger, more like 1.5 hours. Also, SLC didn't have many homeless people, while Seattle attracted most of the homeless people from the PNW, including lots from the nearby reservations and even Alaska (Alaska exports their homeless problems to us and LA).
That McDonalds though --how did you survive?
I worked there in '94 when it was more rundown than it was today. The smell (malt liquor, unwashed clothes, urine) was difficult to handle at first but I got used to it, my coworkers were also pretty cool (mostly filipino/a immigrants) so it wasn't so bad.
My mom (a Ketchikaner) told me this, but I can't find any references; my experiences are also about 20 years out of date now.

Search for "blue ticket", it might not be practiced anymore, I'm not sure; but I believe there was still something like that going on in the 80s at least, and it was definitely a thing while my mom was growing up.
I remember some of the homeless in Seattle were from Alaska, how they got there...I'm sure if you ask a charity you can get a bus/plane ticket in winter easily enough, even if the gov doesn't do it for you.
Seattle has relatively affordable airfare to Anchorage.
To go from ANC to SEA by bus you'd be taking 3 different bus lines, for a total price of ~$425 and probably a week of travel time.

Buses out of Alaska aren't cheap, its much cheaper to fly these days. You can get a ticket to Seattle for < $300. "blue tickets" seem to be ingrained in Alaskan culture, its a word that is understood very well up there; people like Palin use it to trash talk others they want to go. You are right the overt practice is probably not acceptable today, but the philosophy still holds.
