Your “make a friend” comment gave me a chuckle.
Last year, while returning from a visit with family in central PA; I was passing through the TSA pre-check line in Harrisburg. In my carry on bag were a couple Lionel freight cars I’d purchased at a train store in Altoona.
The TSA officer manning the scanner stopped the belt and backed my bag up, then scanned it again. As my bag exited the scanner, he looked at me with a grin and said “a three rail guy, huh?”
