When I was growing up I looked forward to each monthly issue of the Highlights magazine. I liked the entire magazine but mainly was the section called Hidden Pictures. It was fun searching each page for that hidden item. Today we also have apps for our phones where we can do just the same thing but we don't have to wait each month for the next page to search for. The apps have thousands of pictures to search. What fun!
Bogus hint. Keep looking.
Today, you have the opportunity to do a little searching for the hidden coordinates somewhere on this page.
