On a sunny day in May, my hostess and I zoomed out of Bologna on her Vespa arriving at Dozza for the city's annual Wine Festival. The entrance ticket gave us unlimited samples, and so we walked the medieval streets sipping the various regional wines and stopping every now and then for a nibble of prosciutto piadini to soak it all up. One block featured vintage vehicles -- cars scooters and motorcycles -- instead of wine. I liked this guy's bright red bike the best.
