I would love a Ric-o-chet yes....if the price is right.
About the cabs on that ceiling: I remember a thread on KLOV about a barn that was about to collapse.They goto the machines out though a hole in the roof IIRC using a tractor or so....not sure, maybe someone remembers the link
?
I don't remember the link sorry.
I have been spending all day at work thinking about how to save all these games.
I think getting wooden beams or floor boards from a local supplier and then using 'what we call in the UK' Acros - which basically go under the floor beam to support the ceiling may be the best way forward.
Something like this:

Put the wooden beams across the rotted ones under neath, then use the acro units to support it.
kos71 - have you thought about phoning a local builder in the town? He may be able to meet you there for a small cost and actually put these safety units under the floors for you for a small cost. Saves you having to transport all of the equipment to site yourself.
