This Harley-Davidson motorcycle showed up on the Pacific coast of British Columbia in Canada in May 2012. Media reports about this rather unusual find helped trace the owner of the bike.
Other items, such as footballs, bottles, etc. have also shown up the western coast of North America, and are from the same place. A large wave of stuff is expected to show up in 2013 and 2014.
So what's common to where all this stuff is coming from?
