Which of these bike boxes are not like the others?

People can argue and debate the aero benefits and features of different bike designs all they like, but put the boxes they come in on a bike trailer and take them to recycle in a stiff crosswind and the pros and cons are moot points.

Oh yeah, disaster can even strike the car free liver! But (after a photo for blog purposes) there is no need for a scene, a tow truck, a call to the insurance company or even the police. Kicker the tractor, flip the trailer back up and on you are on your way, hoping the wind does not gust again this trip. (it did)
