Unfortunately, there was a stupid Bike Race that closed much of MB drive and all of Fiesta Island. I did a long walk fishing and flew the drone along a lot of beaches, but the really high tide made everything muddy, green, or both. Needless to say I didn't get any good intel, but I will try again this week. I'm also sending out a few guys to check the front of the bay in case something is happening up there.
...but the bats are there.
I'll believe it when I see it. All the rays have been eaten by white sharks or migrated to a far away island, out of reach of any pendulum cast.
