Sharon commented one day that "We sure have lost a lot of grade schools.".
This brought up the questions "How many?" and "Which ones are lost?"
To create a visual answer to those questions I created a small grey tombstone with the letters "RIP".  
This tombstone signifies the school is deceased or no longer functions as a grade school.   It is placed on the push pin head in the Map section & just along side the school name in the Index section.   Using information supplied to me by Wilma (Blewett) Puich, I have displayed the current status of each school immediately following the school picture.
