It is fiction.
Parts of it look autobiographical because the stories that are most compelling are the stories we tell about the about things we are intimately familiar with. I have never been to Portland or Seattle. Unfortunately, it looks like the events happening there will be coming to a town near you in the near future.
But the story is fiction.
Some of the characters are inspired by people close to me. I took all of their good qualities and then had to add a few bad ones to make them seem more real.
Distances are approximate so the my various "inspirations" are not doxxed.
Clearly, the events that are described in this fiction do not need to happen.
