Can you see these vertical lines on my car headlamp?
WHAT has made them?
A snail, maybe? We spotted these weird tracks last November on the bonnet of a car; a bit of research confirmed that they were caused by a snail grazing on the gubbins growing on the car.
Well, that's a maybe - but ol' snaily seems to be going in a remarkably straight line. Perhaps the ones on the silver car were giant drunken snails, and mine was a tee-totaller?
