Interesting story, though I can't say the practice is celebratory. I think there's too much waste in the world, starting from such events where things are like...getting crushed for fun, ending tot he food restaurants throw out. Yet it's an interesting phenomena about the train crashes
I just recently realized that, after moving next to a big park where those big events happens, even the ones self claimed environmental friendly. The next day is so so much garbage of all sorts.
