We used to do this at my Pastors house for Superbowl Sundays. using the side of his neighbors house as the screen.
Imagine, larger than life sized football players coming at you!
I did this a few years ago for my son's birthday party sleepover. I had almost two dozen preteens on the backyard lawn, used two king sized bed sheets strung between two palm trees and a projector, dvd, stereo system, running a STARWARS all night party. My wife was pulling full time duty making pop corn and pouring sodas.
Halfway through the second one, 3/4 of them were asleep! Pop corn bags and cups all over the yard. Kids in sleeping bags all over the place.
It was a blast.
My poor pool was invaded the following day.
Hmmmm.... maybe time for a Pirates of the Caribbean theme party. :idea:
