If you have a need for some rural areas there is some really interesting stuff in central and eastern Washington -generally some places that look unique and unfamiliar (to folks not from Washington at least) may be useful for creating a sci-fi world that doesn't just feel like Seattle with a few special effects.

• Any number of modern looking airbnbs in the middle of nowhere
• Channeled Scablands
• Frenchman Coulee
• Idk what of it could be accessed to film (safely and legally) at but there's all the old Hanford stuff out by Richland
• Plenty of small eastern WA farm towns that basically look abandoned
• Pioneer cemeteries
• Wind farms
• The wheat fields outside of Pullman post harvest will look like a post apocalyptic landscape
• Ghost towns like Bodie
• Leavenworth if you need a scene to take place in Bavaria for some reason or want to trap a character in a simulation thats looks like a tourist trap made up city
