Must do

Am I the only one that gets so into the movie that I probably would forget that I was outside?

[Human No More]

It depends on the conditions. If it was really windy or something then I probably wouldn't, but otherwise I probably would.

You could always make a screen out of 12 pieces of foamcore board taped together on the back...

This is a great idea. I wish I had a projector.

This is actually the best idea ever. I'd love to do this one day! Depending on the weather of course... Could be difficult in the snow belt of canada.
