Yeah, shallow river sounds like it holds some “deep” history, pun intended. Congrats on your instructor license, that is a very serious accolade and qualification to have to help guide others in this field of work, passion and operation. Yes, one day, I will dive, and try to not picture me in a JAWs shark film, being eviscerated and snuck up from behind. All I picture is murky bloody waters. I commend your bravery. If they ever create Reinforced Titanium Diamond scuba diving suits that can withstand the bite pressure of the largest Great White Sharks, then I will join you next week!
