[georgie]

a little spur of the moment mooch up top of this thing in the east float dock, the fog was getting really thick it was nice and sunny at one point

heres what its use is for...

The Caission is used to close Dock / Lock entrances when the gates are off and being repaired. It is floated over the lock / dock entrance and then flooded down onto the gates threshold where it seals the entrance to the waters.

mooched with the cat
