You've definitely seen horses being transported on the highway before, with their tails visible in the back of the trailers, but now an Idaho rancher has created a whole new way to transport his horse-- in a homemade motorcycle side car. A video filmed on a road in Shoshone shows Casey Perkins riding his motorcycle while his horse rides next to him in a homemade side car. His wife filmed the video and notes in her caption that her husband "started this whole deal a little over a year ago when he decided to modify the family van and hauled his horse in it."(UPI)
