Vintage red trolleys and horse-drawn carriages still roll through the streets of St. Louis. Though sometimes caused by a rip in the space-time vortex, more often than not they're part of the St. Louis Carriage & Trolley Company's leisurely history tours. A certified guide leads these trips in trolley busses or carriages drawn by some of the company's 17 elegant horses, including Percheron draft horses, one Clydesdale, and one Belgium. The tours—which can be customized—pass sites such as Union Station, Peabody Opera House, and the picturesque Laclede's Landing.
