I've heard about a custom that used to be performed in the Czech Republic in the spring. I think it's meant to celebrate the end of the winter. I am not sure if I'm correct, but based on what I've heard, all the people living in the same village get together, form a procession and walk to the nearest creek or river to throw a straw doll that symbolizes the Winter in the water to "drown it". Is this true and is the custom still performed? Thanks!
