The story behind this is that when my little sister and I were kids, we invented a game called Blammer. You duct tape small trashcans to your back and try to slam a sock ball into your opponents basket. We used tennis rackets for defense. We used to terrorize our parents with all the running and yelling in the house. We're in our 30's now and try and play when we see each other. I call her Chicken and she calls me Ducky. Which is why we're are riding birds. One of my favorite pieces I've ever done. A birthday present for her.
