A June Easter egg hunt?

State Rep. Paul Amador and his wife, Julie, encountered an usual sight as they walked on the trail along Ramsey Park Thursday:

“We were on the trail next to Ramsey park and I noticed an egg at the base of a tree and pointed it out to my wife. Then we realized there were dozens of them throughout the park. When we got closer we saw that most of them had messages written on them “throw me” etc. I’m guessing local high school students because one of them had “94%=B”. I guess we just need to find out which h.s. teacher in Coeur d’Alene gives a B for a 94% and then which student earned a 94% in the class this semester! I don’t know much else about the background of the story. I sent a message to Mayor Widmeyer to make sure someone from the Parks Department got over there before we had any eggs thrown at passing cars or cyclists!”

Question: What do you think is going on here?
