The thumbnail photo is Cinco de Mayo.
It's May Day! I lived in Japan for three years when I was a child and this always brings back memories. The first year we lived there we didn't know that it was the day the leftwing hordes rioted in Tokyo. My sister and I were at a theater downtown, where we suddenly started hearing the sounds of people shouting and cars being pushed into the Imperial Moat. An American soldier quickly bundled us into a jeep and drove us home. We never left the house on May Day again.
