First flight in a knee hanger harness, which allows for flight in a prone position. I was so enthralled/excited by flying prone (WHEE!) that I (1) completely forgot to cross my legs the entire flight and (2) forgot to practice transitioning from prone to horizontal on the ride down, so I just rolled it in on the landing rather than try to get vertical in the harness for the first time for a foot landing while in the box pattern.
