Barney and Latour, both recent high school graduates, are from Oswego, New York, and just passed through Cleveland as they attempt to travel all the way to Seattle, Washington on a custom-built skateboard -- and a mountain bike.

The twosome said they are making the trip of a lifetime to encourage the use of non-motorized transportation methods and raise concern about environmental issues.

"We're trying to raise awareness about the current state of our oceans," said Barney, referring specifically to the masses of floating trash known as "garbage islands" polluting the world's open waters.

"Everybody, please pick up one piece of trash, at least, a day," implored Latour. "We do it. We pick up trash all the time."
