Carole and I celebrate the heroes who unified Italy and made it what it is today -- a boot shape with lots of pasta.

On our way to warm up at The Trout, a cozy pub near Oxford, on a typically raw day. This part of the path was flooded, so my friend Nick suggested we save our boots and brave the waters barefoot. Brrr!
