Metro is a former racehorse that was adopted by artist Ron Krajewski. A vet said Metro couldn't be ridden and had just a few years left due to badly damaged knees.

Ron wanted to spend quality time with Metro, so decided to teach him how to paint. The art was put on sale in a local gallery in Gettysburg, Pennsylvania. It proved so popular it paid for experimental treatment, which has added years to Metro's life.
