There aren't many drive-in theaters left in the US—none near NYC—so Bryan Kennedy decided to create MobMov, a drive-in theater that drives in:
Participating in a mobmov is very similar to attending a drive-in from the days of old, except now the projector is located inside and powered by a car, and the audio is piped in stereo over the FM band to the attendees' cars. As a mobmov driver, you assemble the kit, decide on the movies, and announce your showings to friends and the community at large. Then everyone assembles in a dark place with a big wall, and you watch a movie. It's a new technological twist to a nostalgic idea.
Sounds like something you might like to do? Kennedy's put together a fairly comprehensive tutorial on starting your own MobMov, from how to choose a projector and FM transmitter and how to set them up in your car, to how to design the intermission and provide snacks, all the way to making sure what you're doing is actually legal.
