This was one of the vehicles clearing snow from the road up to Etna. It sat in the car park next to the restaurant we stopped at for coffee before heading back down the mountain. I thought it would make an interesting picture (we rarely see snow chains on the southern English coast!).
killing time with a camera ... 
Nice, crisp isolation of the chains on the tire.
Very cool shot.
Love your composition, those chains look great!
I really like this image. Your composition and those snow chains are just wonderful.
