I spent the better part of last week on a mini vacation that included a little camping trip. While there, we broke out a projector and white blanket and had ourselves a movie night by the campfire. Although it was a bit on the makeshift side, (i.e; ghetto) it was a whole lot of fun! And so to anyone that already has a backyard, a white sheet and access to a projector, I highly recommend turning your yard into a theater.

Design Sponge suggested an outdoor movie night about a year ago:
