Rails

does anyone have any idea how to set up rails or sliders in the water....is it as easy as just digging a hole and putting it in or is there a special way of doing it

You can just beat it down in the mud or the best way if you can is to take a water hose and put it right beside you post with the tip at the bottom spraying down into the mud. This cause the mud to move out of the way and will pack back around your post as you keep pushing it in further down. This is how they set post for piers. Digging a hole in the water dosent really do anything.
