yeah seen that on a few MC boards... at least the guy had the decency to put a helmet on her. i've seen women jump on the backs of bikes thinking they can go for a "ride" just like they can in a car. on a MC you have to actively "RIDE" the thing and far too many guys will allow girls on the back of their bikes with little to no training on how to be a passenger. its sad to see this as the poor girl probably never expected that she'd fall off the back
