Just when you might have thought the Winter Guessing Game had gotten to be a relaxing daily challenge, something akin to a level 2 sodoku puzzle, we throw something harder your way. Though this photo comes from jolly old Chicago, that toddling town, the photo comes courtesy of Solo_Racer, who used to pilot this winter beater when it was too cold or snowy for motorcycle travel. It's cropped so devilishly we wish we'd have snapped the photo of this rusty classic. We'll give you a hint: it's not a VW Jetta.

Of course, if it's too hard for all of you we've got a couple of larger pictures. But what's the fun in that?

What is it?
