Hi guitarguy86. It's great to meet the other pipe smoker in a 50 mile radius!
Being located in the Grass Valley/Auburn area, I recently went through this search as well. The only real tobacconist in the area is
Briar Patch. They're located in Sacramento. There's 2 locations, one in the Arden Fair mall and one nearby in a strip mall. They have a good selection of pipes and tobaccos as well as a fun and knowledgeable staff. Make sure you bring your pipe when you go because it's a great place to sit and smoke your pipe and chat with other pipe smokers. The only other place that even resembles a tobacconist is
Perfecto Lounge. It's actually a cigar bar, but they do have a couple of tobaccos. The neat thing about Perfecto Lounge is you can go in, smoke your pipe and drink a beer with like minded people. It's near my work so if I'm running low on tobacco I'll swing by for a pint and pick up a tin. Bear in mind though, when I say limited, it's very limited. Last time I went in they had 5 choices in tinned tobacco and 4 bulk blends... but hey, there's beer.
With that being said, it seems we're the only 2 pipe smokers in the Sierra Foothills, we should meet up a Perfecto Lounge or some other smoker friendly establishment and drink a pint and swap stories. PM me if you're interested.
If there are any other pipe smokers in the greater Auburn/Grass Valley/Nevada City area, please pipe in and we'll all meet.
