I am reading about all the plugs forgotten and I am thinking what can I do so it doesn't happen to me and it occurs to me that a valve would be great. Of course I am too cheap to buy one so I was wondering if a piece of innertube glued to the outside of the trasom over the plug hole would help. It would seem it would reduce the speed the water went in the boat. Of course you would want to use a plug, but it would seem it would help reduce the stupid human posts. Color it hunters orange so it is obvious maybe. <br />Any thoughts?
