After an interesting dive at Hole in the Wall, we had all of our back gas left, so we decided to do a swim dive over at Twin Caves. Unfortunately a few people on scooters had blitzed the viz in the subway tunnel, so we’d have to deal with <15ft of viz in some places until we could drop down to the right side of the T, where we had been told there was clear viz until the double arrows. This is my least favorite dive on the Mill Pond due to how little the first 900ft of the cave change, but it’s still a neat little dive to do if you want to kill time.
