I took this photo on the beach in Ocean City, New Jersey, several years ago. I did enhance the sign a bit so it was more readable. People don’t drive on the beach there, so I am not sure who they don’t want to exceed 5 mph. Perhaps the trash cart? Seagulls? Crabs? Me, carrying tons of stuff, burning my feet on the sand? I am pretty sure though, I would want the life guard to haul ass if I was drowning. Gotta love the random sign.
