Seth and Bob, regarding the topics I've posted, usually it's a mystery to me how ideas for them come to mind. This reminds me of when I was active writing songs and coming up with subjects and titles for them, which usually came to me mysteriously.
The title for this Forum topic was not a mystery. When I heard infrastructure mentioned in the news this morning, I had the amusing thought that model railroaders like us can post how we have developed infrastructure for our layouts, which can inspire our nation's leaders when they vote in Congress on infrastructure.
Getting that amusing thought when I listened to the morning news - that is a mystery to me. Arnold
