There's only one herp vet in Spokane that sees snakes and that's the lady I went to see. I kid you not, I called every vet I could find in the phonebook when Nergal needed to be seen. NONE of them saw herps, and if they did, it was geckos or turtles. Only this lady did.
Spokane sucks. The nearest area I know of that has a semi-large population, large enough for a snake vet, is Coure d'Alene. I'll look it up. I live in the side of the state closest to Idaho, and there's NO large cities on this side--everything is by Seattle on the opposite side.
