Not sure if there was any singing going on outside the impromptu karaoke when we were setting up. There was, however, a swearing steersperson who feels chagrined at cursing out the team that spun his boat and then hit him again at one of the turns. Note to all you seat one paddlers: please help your steerer by keeping your heads up and drawing left or right to avoid a collision.
Oh, and Lethal Weapon took some great photos:
