Diving is a fun sport that takes some time to practice and get comfortable with. I don't go to super deep narcosis levels but I do like to get out as much as possible. I'm fixing my little dinghy boat with liquid rubber coating so I can rig it to dive off of it. There are a number of ship wrecks and other places to explore along the water front in Delta County Michigan. I keep trying to find new places to explore and test. This was near the municipal dock. Its an hold ship hatch or door or something. Mostly rusted out.
