Horse Power was a great show! I watched it from beginning to end, had them taped and have watched them dozens of times, and have ordered the DVD from the Discovery Store. As a competitive hunter/jumper rider, I found this show to be both educational and interesting.
The girls who rode in the 2005 Maclay are all fantastic riders. The show introduces us in-depth to 6 girls and 1 boy: Brianne the "favorite," Maria the catch rider, the unpredictable Chelsea, the egotistical Nikko, Lindsay the underdog, Natalie the eldest, and Maggie the "wonder kid." The show gives a nice variety of people...5 are from two different elite show barns, one is trained by his mother, and another lives on a farm. However, they are all extremely competitive and excellent riders.
I definitely recommend it for anyone who loves horses.
