On the north side of the airport off of Boomer Street, you will find the Marine Corps League Aero Park. This facility has been developed by the Watertown Marine Corps League and serves multiple purposes. First and foremost, it is a memorial to fallen Marines with life-sized statues and plaques commemorating various Marine Corps activities. It also includes a 911 memorial to those who fell when the World Trade Center was attacked on September 11, 2001. Additionally, it includes a pavilion and restroom facilities, which makes it a great place to have a picnic.
While at the park, you can listen to the plane transmissions on 107.9. There is also a drop box for old flags that need to be destroyed.
Please show respect while in this park - the cache is not located on or near the monuments.
