WASHINGTON - A raccoon was caught on camera hitching a free ride on the back of Washington, DC, bus cruising the National Mall. The National Park Service's Mall and Memorial Parks Facebook page posted a photo showing the freeloading trash panda peering through a window while clinging to the back of the DC Circulator bus. "Look who decided to take a ride on the bus!" the post said. "Take the D.C. Circulator National Mall Route around National Mall and Memorial Parks," the service wrote. "It's only a dollar! Spotting wildlife is not guaranteed." - Agencies
