Chad, we found that spot last year and did the emergency stop. Stuck my head over the windshield and smacked into the tower, which pushed the temples of my shades into flesh and spewed blood.
All because, and I quote, "so calm and clear in there that you can usually see the sand below you as you ride even though it's 15 feet deep or so."
The sliders looked pretty scary then though. Figured they had hepatitis written all over 'em ;-)
