On the way out, I asked them to wait while I ran up to EL Capitan, a 36 rock of 3,300 feet straight up. I touched that giant rock and knew 37 I wanted to climb it.

Each year volunteers come for the cleanup from everywhere. In 2007 alone, 2,945 people picked up 42,330 pounds of trash and 51 132 miles of roadway. I often hear people 52 about their surroundings. If you are one of them, I would say the only way to change things is by 53 rather than complaining. We need to teach by 54 .
