After this dive, we ascended near a few boats that were exiting the water. Turns out someone in one boat threw their keys to someone in another boat and missed. We hopped onto one of the boats, they drove us over to the cove where they lost said keys and we rolled off of the boat and into the water, Joe found their keys in about 10' of water in about 1 minute.
Before that we were playing around in the sunken cabin cruiser, which looks way creepier at night.
