There is one head shop that I know of, that is hoping to delve into better
vaping supplies. I haven't tried since last year, to find a local though, so maybe there's more by now? The cigar/tobacco places weren't any help at that time, but perhaps they've seen the light by now. Try both the Head shops and the cigar shops.
What type of
vaping gear are you looking for? I might be up that way next next week. (I'm in Mendocino county). If I have extras of what you need, I'll be more than happy to drop something off to you. /Where are you? SoHum? Arcata? in between?
Nice to meet a "local"!
