When I first started out hobby engineering I volunteered at a small local railway museum. It was an interesting place full of nice and knowleadgeable people but I had some trouble with the guy running the show.
But man, they had a cargo container out the back that was just jammed full of these kinds of things. Supposedly alot of businesses donated the stuff, but they had no use for near all of it and it just got mothballed.
I'm always tempted to go back to that museum, but I figure it won't take long till I get intro trouble over nothing again. One guy got upset at me for doing a job too quick, he thought I was lying when I told him i'd finished and blew his top when I said it wouldn't hurt to apologise. The boss man himself got really upset when I told him I'd volunteered to have fun, becuase he couldn't understand the idea of somebody enjoying work. I guess it only takes a couple of people to ruin an otherwise great thing.
