I like diversity on decatur. There stuff seems a little expensive though. I refuse to go to any of those arab smoke shops that are in about every strip mall in the valley.
There are a few people on this site who blow and sell glass. I know @researchkitty is one, but I think there are others. I've never bought anything from any of them but it seems like a cool way to buy pieces. A lot of the stuff in smoke shops is made for cheap in china now. I'd rather buy from some hippies personally.
