Drive-Ins are making a comeback (as an underground guerrilla movement). Guerrilla Drive-In movements are apparently popping up all around the country. The idea is, basically, some guy drags a movie projector and a radio transmitter to a place with a nice wall and shows a movie. The place where the movie will be shown is predetermined and people are informed by mailing list, website or any other if-you-know-where-to-look method. To view a movie, you show up at the specified place and time and tune in to the movie's radio station. Santa Cruz Guerrilla Drive-In seems to be the first, most popular or just most well known group running Guerrilla Drive-Ins and they have links up to a number of other similar groups in other parts of the country.
As of yet, there does not appear to be a group running Drive-Ins in New England (specifically Eastern Massachusetts) but if I find any, I'll let you know. Or, if any of you hear of any or decide to start one, drop me a line and I'll come watch and maybe help out.
For that matter, if I can get my hands on a high luminosity projector, I will personally obtain everything else that is needed and found a Guerrilla Drive-In for Eastern Massachusetts. (Anyone want to donate an old, working projector to the cause?)
