Me too Wow. I moved into an office in a class "A" office building that had a funny floor in an inside room. Turned out it had a 10g steel plate under it. The room had been used to house a high density file system, and the floors were only rated for 150# sq/ft, so thry had put in the plate to distribute the load.

There is also the legendary story of the San Antonio law firm that moved all their legal books into their brand newly renovated second floor library. Whe they got there Sunday morning to finich unpacking, the library was in the first floor garage. No lawer jokes, please.
