Indeed why go to a large gathering of warsie nerds who dress up as stormtroopers and kiss Lucas ass the sycophants, when the original films are locked up in skwalker ranch and he won't release them.
Lets pay money to the almighty bearded one and worship him. And celebrate the destruction of the oot.
You can also use the opportunity to network with the people who will one day revive the movie you believe is lost. There's space at or near the event to do your own thing. (but i'm only judging from being at the last one) I was able, without any hassle, to hand out several hundred strange DVDs, (to all levels of fandom) a similar thing can happen at the next one, to an even greater level.
and the projection idea is something to really consider, would need some help, please suggest tech here:
