Listens: Devo interview

what is it about seattle?

I think Ive asked this question before

Sci fi writers in the 70's through to the 90's liked nuking Seattle.... why?

But now since the turn of the century/millennia chicago is the one getting whacked in sci fi stories.

Im reading another sci fi series Harry Turtledove's balance WW2 series where chicago gets whacked I was going to post about this as proof as an on going trend but I read further and lo and behold Seattle gets whacked by an alien nuke (chicago got whacked after a stalingradesque  fight for the city and the bomb was detonated by the US army)

so what is it about seattle and chicago?
