Thoughts on Stage Floors

Let's talk about stage floors for a moment because they don't always get the attention they deserve.  The floor of the stage serves two important purposes: it's the working surface for performers and it's the attachment surface to brace or lock down scenery.  These functions have very different requirements, but both have to be worked into the floor design.  Here's why.
