Thank you Bear Islander and Hazelnut. I enjoyed both of your presentations very much. BI made suggestions to control the lake vessels' speeds, HN suggests better boater education and patrol enforcement. Both "corners" recognize the other's argument but obviously are committed to their cause.
Something we used to do in school at this point was to change sides and argue your opponent's position. Obviously the practice is to argue to win (not the try to see who hits the softest .. oops you win
)
