Moonbeam Outdoor Cinema

 is a broken-down outdoor theater with a few cars and picnic tables. It seems to be a small base for Super Mutants, staging attacks nearby Big Town.

This is one of the possible locations The Family is said to have been seen at, but unfortunately the wrong location.

Location

 * Directly northwest of Big Town, far northwest of Springvale.
 * Directly east of Fordham Flash Memorial Field and Arefu.
 * Southeast of Hamilton's Hideaway and Northwest Seneca Station.

Inhabitants
One Super Mutant amongst the picnic tables, and a Super Mutant Brute armed with a Minigun hiding in a nearby trailer. He has also been seen using a Missile Launcher as well. You can be ambushed by a Mirelurk Hunter and mirelurks if you explore it in Blood ties.

Hint: Shooting the vehicles will set of a series of explosions, killing any enemies or yourself in the process

Notable Loot
There is a Pugilism Illustrated on a picnic table in the middle part of this area, north of the theater screen and on top of a Large Destroyed Book.
