The first thing that hits your snout when you walk in the door is the intoxicating scent of hundreds of pairs of new leather boots. Then you notice the studded dog collars, horse whips, chaps in assorted primary colors, tubes of "ultrafine horse glitter." A South Beach fetish shop you haven't heard of? Nah, just a one-stop shop for horse owners, dog lovers, wild-bird feeders, and people who can't own too many large silver belt buckles. As you browse the astonishing array of avian comestibles ("Classic Finch," "Fancy wild bird w/corn," or "D'lux wild bird -- no corn"), chew hooves for dogs, and calf ropes, keep your eyes peeled for a sweaty ten-gallon hat and your ears tuned to the sound of jangling spurs. Still owned by the same family, now in its third generation, Sunset Feed & Supply opened in 1960, back when cowboys were REAL cowboys.
