This is a head shop? Where are the shelves lined with vibrators and dildos? How nice it is to venture into a store catering to fans of the herb that doesn't treat tokers like they're one skeevy step away from being a perv. Browse through the collection of retro-style clothing, art, jewelry, tchotchkes and incense and you may forget why you're there — to blow bucks on an original, artfully blown, hand-crafted "water pipe." (Of course, "water pipe" fans are liable to forget lots of things.) No worries though, Retro has a vast array of pipes, extractors, papers, jars, grinders and all the other accoutrements needed to keep the hippie in you happy. Well, all but one. This ain't California.
