This is my friend Andy and his cabin cruiser. 
During a flood in 1995 we decided to take his boat upstream in the flood waters of Stones River from Mona Boat Ramp to Walter Hill Dam.
Normal days you can wade across the river below the dam. Crazy, yes but it was a fun trip, so I called my wife on a CELL PHONE and she showed up to film this event.
This was a VHS Recorder if you are interested in he real time line and the cell phone was analog. The water speed was about 15 MPH so we had to go faster than that to maintain control back down stream.
