I have some family in North and South parts of Idaho. Have considered moving to North area, but will stay in Washington until it is too dangerous (politically) to stay here. Much of my family has already left WA for ID, and maybe that day will come soon for me to jump ship.
In the meantime, I'm opening an airgun shop in Vancouver, WA, but plan to sustain the rent with some other side-projects (photography darkroom, b2b services). It's unclear how much revenue can be provided for air guns, alone, and I'm trying to get my FFL, too. There are many more people in Portland, but there's an aversion to shopping in WA, since they recently canceled the sales tax exemption for Oregon residents.
I'll see if my family has any interest. Hoping to travel out there in the next couple months as well. If you end up opening shop, please update with an address!
Good luck!
