My dad and his buddy used to try to scuba with the glass battery cover in a deep stock dam They had a hose run up under it and everything. :wink:
Dad said it was pretty hard to swim down, bet they wish they'd have thought of pushing each other down, but I think it's deeper than that, may not have worked. :roll:
Northern Rancher looks like you must be a pretty fun dad, always got those kids into something interesting. :lol: :wink:
Have a good one!
