As a friend said, not to be confused with a Grand Opening. I do believe this sign on a window of an old industrial or factory-looking building no longer holds its original meaning. Then again, what is a ‘fire opening’? Not really sure. I took this photo out the window while my daughter was driving. I had her pull over so I could frame it from a standstill, though it’s still not straight in the frame. I will return for this one with the Nikon at some point.
