Back in the mid 80's, my Dad and I were crappie fishing the logs and stumps in the mouth of the Duck River where it enters the Tennessee. We were fishing in 1.5 to 2 foot of water when we heard a bass boat running at high speed getting closer to us.
This fiberglass bass boat came running off the river and headed toward the flat about 300 yards from us when they hit whatever it was they hit. The outboard flew over the boat and the whole transom went with it.
When they stopped, the two guys got out of the boat and were standing in about a foot of water.
They seemed to be unhurt, slogging through the mud and Dad said " We should probably go help them, but they are so stupid, I really don't want to deal with them"
We kept on fishing...
