Richard Mills, left, riding Willy, a Tennessee walking horse, and Ryan Rollins, riding Blondie, a palomino, head west along the flood wall near the Falls of the Ohio in Clarksville on Saturday morning. Saturday's ride was the first leg of a 3-4 month journey for Mills to raise awareness and funds for neglected and abused horses. He plans to ride about 25 miles a day until he reaches Great Falls, Mont., while following the route that Lewis and Clark used for their exploration of the West in the 19th century.
