The photo above was a capture of sleeper I brought and used at the summit of Mount Maculot. The picture was taken last June 13, 2009 during the night where the group was having fun at social activities.
One thing struck my mind in this sleeper, well there was a written message "think green planet". It seems the message and the sleeper convey contradicting ideas. "think green planet" leads to taking care of environment while the sleeper was made using a rubber material which appears to have issues againts the safety of environment.
