The Deertrees Theater in Harrison, ME was abandoned for years. Back in the late 80s, people decided to fix it up and get it open again. some friends and I had tickets to the first show of the new era (a screening of a great Lillian Gish silent movie called "Way Down East") and took a trip to it in the daytime so we'd be able to find it that evening (it was out in the woods on an old dirt road). While we were there, an old man that had played there in his younger days showed up and ended up giving us a tour and history of the place. It was in horrible shape, but had tons of character and a great history. Toward the end of the tour, some guys showed up with a piano (to accompany the silent movie) and we ended up helping them move it. The old man turned out to be the piano player for the movie.
The movie was great and it was strange to sit in a theater watching it while seeing stars through the holes in the roof. The theater has since been fully repaired and it's a great place to catch a show.
