I'm something of an air hog at this point!
By "rickety pallet," I assume you mean the platform? Didn't seem rickety to me! At least the buoys were both back in place (one was missing recently), which made the PVC bars every 15 feet list sideways like they were drunken, or so I'm told. We did our safety stop on the bar under the south dock (there's one under the west dock, too), as we went on a tour of the wall after we came up out of the hole. I'm glad the black sulfur layer at 60ft, which turned the hole into a dark as night pit, wasn't there. Viz was about 10ft, but the sun was out so we had some light.
