I grew up on a farm in the Thumb of our great state of Michigan. We had about 200 cattle on the farm at any given time, not once did we ever ride or even think about riding a cow. Not the same can be said for 15-year-old Regina Mayer in Germany. Read more and watch the video after the jump. Mom and dad wouldn't buy her a horse so she decided to use the next best thing a cow.Through training and treats, the cow can do jumps over hurdles and go for rides in the countryside.
