Richard Mills preps Willy, a Tennessee walking horse, on Saturday morning in Clarksville before embarking on a 3-4 month ride, starting at the Falls of the Ohio and ending in Great Falls, Mont. Mills is making the journey to raise awareness and funds for neglected and abused horses. He plans to ride about 25 miles a day following the trail that Lewis and Clark used for their exploration of the West in the 19th century. Staff photo by Christopher Fryer
