Richard and Greg, Thanks to your sharp eyes you have helped divert disaster in my home!
I'm convinced there are evil forces in the universe that cause screws to become deregulated if not constantly monitored. To all you naysayers,
check your switch cover screws as you head to the kitchen for that second cup of coffee this morning!
After verifying your observation, I broke out the required tools and made a complete sweep of the house. Many other deregulations were found and corrected. There now is a calm, restfull atmosphere in the house as all is well in the cosmos.Photographic evidence provided below.
P.S. Have happily noted that Parker shot guns kept stored in their gun cabinets do not suffer from this afflicion!
