My oldest, Heather, just returned home from her third trip to Italy, the last two as a nanny.  Having a goodly amount of free time, she took advantage by traveling to various cities in Italy, and extended trips to England and Switzerland.  During a hike in the Alps, she and her friends encountered a herd of very happy and amazingly CLEAN cows, afterward posting a video which included their melodious cowbells in "concerto".  Of course I just had to have "more cowbell" to help ring in her birthday. :)
