BOULDER - Police have arrested a man suspected of going on a drunken horseback ride through the city of Boulder.

Patrick Schumacher is facing charges of riding a horse while under the influence of alcohol after witnesses saw the rider and horse occasional wandering into traffic on Broadway near the school Monday afternoon. 

Officers observed that Schumacher was slumped to his right side as he crossed streets and forced pedestrians off the sidewalk.
