I often head over from Norman early to dive the WillyT. It’s not unusual to see both balls occupied and not a dive tank in sight or a person for that matter as everyone is sleeping! People get belligerent when asked to leave after you wake them up. Last time one ball was open and we grabbed it. Shortly after a dive boat showed up and the discussion appeared to get nasty as we went under. When we surfaced the dive boat was on the ball.
