I've been finding quite a few radiator caps on the road... and oddly no cars stopped to the side down the road! Also because of frequent fender benders, the sides of the roads are full of car debris, mostly front plastic bumpers, parts of headlights and turn signals and the occasional hood emblem stuck to a smashed grill.
Another odd thing, especially for Athens at this time is that a few road-width carved out sections have begun to be patched. I say this because these sections where cut out of the pavement to place cables or plumbing and are filled afterwards with dirt and are usually left since they don't cause any concern with cars or motorcycles, only to bicycles rims. A section of my commutes has three of these and suddenly they where patched up one morning!
