The next day we board another train, we've just gotten off in Lucca
It turned out that this Wednesday was a national holiday (Liberation Day). At the first few stops out of Florence the train began filling up with groups of high school kids bound for the beaches at Viarregio (at the end of the line). By the time we arrived in Lucca they were packed in like sardines, they had a difficult time getting back on the train after they got out to let us off.
