I learned something new today!!!!  That’s always a good day.  I came across the Flint Riverqaurium and learned all about Blue Holes.  This is one of only a few open-air aquariums in the world.  What amazing views there were.  The Native Americans called such places Skywater.  It looks like the aquarium has been here a while and everything is a bit tired, but it still was an interesting place to visit.
