Massapequa Park's McKenna Elementary School is celebrating its 50th Anniversary this year. They are looking for pictures and memorabilia to commemorate the occasion. The group would like to incorporate the past 50 years into a presentation that will showcase the history of the school. If you can provide pictures, newspaper articles, or mementos that can be used to create this show, it would be greatly appreciated by the organizers.
