One thing I noticed about the gulf coast beaches at Marco Island, FL, were they had a high concentration of broken/crushed sea shells among the sand. There were spots were it was all sea shells bits. Walking barefooted in these areas was not pleasant and felt like you feet were suffering a thousand tiny cuts.
This photo was made shooting over the side of one of our lounge chairs on the beach in front of our hotel — this is the stuff you had to walk on to get to the chairs.
The Atlantic coast beaches I’m more familiar with are mostly sand, less shell.
Of note, today is my son’s twenty-ninth birthday — happy birthday, Aaron! It doesn’t seem possible he’s almost thirty. He must be aging much quicker than I am?
