When we went to the seven devils campout, with the intent of rolling rocks. When we found the perfect spot by sheep lake, we started looking for the perfect size of rock to roll first. After finding the biggest, heaviest rock on the hill, we all started pushing as hard as we can to get it to move. after pushing for a couple of seconds, it finally started moving little by little. after a couple more times, it started rolling down the hill. On it;s way down it hit a tree that got hit soo hard that the topp snapped off and floated into the middle of the lake. Then after we stopped laughing, we searched for another huge rock. This one wasn't as hard, but on it's way down it hit a dead tree and completly exploded it. Pine needles flew in every direction. After having our fill of rock rolling, we hiked back to the cars and drove home. We were so tired of our "activities" that we decided to sleep all the way home.
