Poohsticks is a game where you drop sticks on the upstream side of a bridge, and the winner is the one who's stick appears on the downstream side first. It was invented by A. A. Milne, the auther of Winnie The Pooh Today the kids, my wife and I went for a bike ride on the local greenway, and ended up playing poohsticks. The kids liked it so much we played until we ran out of sticks. These are the things childhood memories are made of.
