About a month ago I got a gram of Black Tar hash from the green door in sf for $40/g. Though it was expensive, it was the best hash I've ever had. I know that the club buys it much cheaper because I can get $250 ounces of bubble bag hash, so I'm not willing to spend $40/g again. So does anyone know what method they use to make it? Or does anyone know of a club in the bay area that sells decently priced ounces of it?
