This has been on my mind. Had to back track and find the thread when I saw your post on another thread. What a great experience, thank you for sharing it with the forum.
I'm sure we've all had similar experiences... personally, it took me a few moments to realize I had metal rivets on my boots, and as Id walk and swing certain steps would get close enough to give me a solid tone or two.. I'm sure I looked like a dog chasing its tail a few times.
