Those Places Thursday-the Duquesne cable car

While scanning through the 1976 journal of my grandmother (Ruth McFadden Webb), I found this article about cable cars still running in Pittsburgh:

I don't know when this article was printed or where, but I'm assuming it was around August 1976 since that's where I found it in the journal.  Most likely it was printed in the Fort Worth Star Telegram, unless they subscribed to an additional paper back then.

My question is why she felt this article was worth keeping.  Was it simply because it was a story from home and was reprinted in the local paper?  Did the Duquesne Incline mean something to her?  Did she ride this frequently in her daily life?

I looked it up and the Duquesne Incline is still running.  When I do make my genealogy research trip to the Pittsburgh area, I'll definitely add this to my list of things to do.
