Specialty ammo - Why Spokane?

Somebody please explain to me if it is just coincidence, or else why is it that so many manufacturers or instances of specialty gadget bullets, and exploder bullets all seem to crop up around Spokane, Washington? The ones I know of are: Velt / Velex / Exammo, “Village Metalworks” (Safe Stop bullets), Joe Zambone’s “Magsafe”, and I think one small-time maker called “FX labs”… Gun shows out that way always seem to have this type of ammo in quantity also.

well from the literature that came with the velet bullets…they were manufactured in spokane about a mile from my house. If I get some time I’ll check out the address lol.
