So not actually a sign, but noteworthy all the same.
The fourth line of the warning is the one you want to read. In case you can't read it, here is what it says: "No Electrocuting, Poisoning or Bombing of Fish. No Vendors."
I did, at one point, almost run over a crab. My first thought was, "AAH! CRAB!" closely followed by, "Crab sign with the halo! Aah!"
The exclamation point is the best part. Also, you probably can't see it, but my scooter helmet is awesome. It says, "Iron Man." Upside-down.
I just couldn't get enough of these "Cliff!" signs.
Anyway, that's all for now. Over and out.
