My friend has one of those pools that you can take down in the winter and the deck reaches all the way around the pool like a circle so theres just an empty space of sand in the middle like our own little boxing ring, we didnt have real gloves so we used those big hulk hand and we just box each other, it was pretty fun sometimes we used to get a whole bunch of people from around the neighborhood and wed set up little brackets and have a mini tourney, good times good times.
