Great - a resounding vote from a notable non-hoarder! :-)
We'll grab whatever we can, time and effort permitting. I believe John can only be there until 3, so it may depend on how many hands we have available to help...
They also have boxes and boxes with old IR security equipment that is probably useless now. Very rudimentary 90's gear: just an IR LED and sensor on the inside. Came from a company making this stuff, so there's also boxes full of headlamp-type reflectors etc (not the pretty round ones Cere is interested in; just angular pieces of reflective plastic). If we get tired or run out of time, I'd vote to leave that stuff behind.
