HOW MANY SQUARES CAN YOU FIND?

Congratulations to Cadet Karen Santamaria for correctly answering that there are 40 squares in the diagram below.  Karen is the first freshman to correctly answer a challenge this year.  BZ!

Here's a new challenge...how many squares can you find below:

This challenge will close out at 0730, Wednesday, 24 October.  The winner will receive one soda.  Good luck.  Notice that the squares are empty--much like my file of pictures taken at the dining-in.  Thanks, PAO!
