“Have you ever tired to buy a Whitworth nut in Grand Rapids Michigan on Sunday morning of Memorial Day weekend?”
I’d have to think about that...but it does sound like a refreshing challenge!
I actually was able to buy one. I was directed to one of the only auto parts stores that was open. Of course he didn't have one. However, the store happened to be across the street from a Triumph motorcycle dealership, and the owner happened to stop by and go in while I was there. He obligingly sold me the Withworth nut.
