I like this Shannon’s May Day hat because it captures what May is about for me. The green and the flowers. However, there’s a darker side to May Day, the first of May. In the night (technically still the 30th of April), Young protesters in the big cities will go out in the night and basically trash other people’s property.
Along the Rhine valley, young men will go off into the woods in the night to cut a birch tree, climb up to stick it into the chimney of the house where their Sweethearts live. Very dangerous, yes, but that seems to have been the point. (A nice knit cap would be handy to have in either case!)
Some towns and cities also put up Maypoles(Maibäume) to mark the start of May and the Mayfestival period (Did I not tell you Germans love a good party?)
