Well a quick Google search indicates that there once were 92 drive-in theaters in Massachusetts but now there are only 3 left!

For those of us born before 1970 (no not me, yeah right!) we have distinct memories of family times at the drive-in. Mine involve running around with my sister and dog in the field prior to the first show, eating lots of popcorn then after an hour or two being told "you girls get to sleep back there now." We were not supposed to be awake to see any adult stuff during the second show. If my father even witnessed us pop our heads up to see some "adult stuff" we would never hear the end of it. I think I also recall one teenage memory that I won't get into here...
At this time there are just three remaining drive-ins: one on the Cape in Wellfleet, one nearby in Mendon, and one in Leicester. The Mendon Drive-In is a great place to go with a group of friends or as a birthday party spot. It is conveniently located on Rt. 16 just 10 minutes from Franklin and is spacious enough for the kids to run around prior to the start of the first show. Some of our son's best birthday party memories include fun with friends at this drive-in. They are open 7 days a week, rain or shine at a reasonable $20 per carload. The box office opens at 6:30pm. Here is some history from their website:
"The MendonTwin Drive-in was built in 1953 and opened on June 14, 1954. The drive-in has been in operation since 1954. The current owners, Susan Swanson and Kathy Gorman have operated the drive-in since 1987. Sue and Kathy added a second screen in 1998, increasing the total capacity of the drive-in to 800 cars. Our projection booth is equipped with the latest in sound and picture technology, ensuring our customers the most pleasant movie experience. The sound is broadcasted over AM/FM stereo, either from your car radio or any portable stereo you wish to bring. Feel free to bring soft Frisbees, balls, etc."
