Went for a 2 hour row this morning. Was a HOT one. A couple of times I stopped to take a water break and heard an add noise coming through the hull of the Whitehall. Almost like popcorn popping. No other boats around.
Only happened a couple times. Think I need to bring along a cast net next time. I’ve heard that shrimp do make a similar sound.

Another sound I heard was the warning siren at Paris Island for “black flag conditions” I think then they get to a certain heat/humidity they limit training activity. I know when I got done I could wring my shirt and shorts out!
