All righty, I shall now be on my way to do a couple of errands and then begin rehearsals.
We're going to try the thing in front of the lens business - to me, it's the easiest way to get this to work. It would involve building some sort of hinged wood piece that would attach to what's holding the projector, and then it would have to be a pulley system that goes to the booth - that way, the SM can pull it to lift it - tie it - then release it when he's through. Tricky, but probably our only out, save for some projector thing that some expert can tell us.
