I remembered this as I watched a crab cross the street the other day.  Human rescue isn’t the only rescue service I’ve been involved in.  Several years ago when I was volunteering for my own emergency animal rescue I received a call for a crab blocking the exit door at a local Kmart.  On arrival I could see a large group of people gathered at the exit doors but not trying to leave.  The exit doors were opening and closing continuously as a Florida blue crab moved back and forth in front of them.  As the doors would open or close the crab would keep moving in a straight line.  It was funny to see how it had everyone stopped at the exit as if the crab was going to attack or something.  I was surprised no one snatched it up and made a meal out of it.  I threw my hat over it then caught it in a net and took it to a canal next to the store. -13
