From their site: "In the spring of 2013, members of the U.S. Coast Guard will drive an electrically powered cart across America. The drive will be completed to solicit the public's support and raise awareness to help support the injured service members of the Wounded Warrior Project."
Besides what I've read here, I really don't know anything about this project. This seems to be an interesting (and fun for those involved) way to earn support for the Wounded Warrior Project.
