I guess nobody read my post about jet ski and tow sleds. Here on Oahu we have plenty of those posted around the Island, manned by our lifeguard crews, for the purpose of high surf rescue jobs. Jet ski's get into very shallow water. Our lifeguards (who I think are the worlds finest, by the way), have pulled people out of 40 foot surf conditions who have suffered broken necks, broken backs, broken limbs, major puncture wounds, and still got em back to dry land alive. IMHO, any lowlying town along any major waterway ought to have at least some similar type setup for when the flood arives. I know its too late for New Orleans now, but how many times have we seen ariel shots on tv of flooded areas along the Mississippi river? Seems like every other year or so.
