On one hand, we hate the idea or horses being used as engines to carry tourists around city streets; on the other hand, these bitches are batshit. See, it seems Peta (AKA: the National Organization of Helping Pamela Anderson's Breasts Put a Stop to KFC's Savoriness) sent an "urgent letter" to San Francisco Mayor Gavin Newsom and the Board of Supes, asking them them to ban horse-drawn carriages throughout San Francisco. This comes on the heels of a spooked carriage horse running amok this past weekend, injuring several passersby. According to PETA director Debbie Leahy, "Forcing horses to pull heavy loads through busy city streets is cruel, and it's an accident waiting to happen ... This incident should be a wake-up call for the city, and we urge officials to ban these rides before the next accident occurs." UPDATE: SFist asked Newsom's office what they thought of PETA's request. Newsom spokesperson Nathan Ballard (brilliantly) told us, "Next they’ll be asking us to ban cobblestones, monocles, hoop skirts, top hats and gas lamps!" (Well said, Nathan.)
