DNR and DFW are definite starting points. You might not even need a degree for some of their seasonal gigs. But don’t forget about Dept of Ecology, too.

If you move down to Olympia, you could also go to school at Evergreen. They have a lot of course offerings that intersect with your interests, and they’re fantastic for working, non-traditional college students. And cheap.

Evergreen isn’t for everybody, but it’s definitely worth looking into.

Good luck! I have faith that you’ll find work that you enjoy, because you’re clearly being strategic about getting there.

TLDR: don’t wait until you have a degree to start angling toward the field you want to work in. You can take steps now.
