I can't answer your question, as I'm not in that area. I did enjoy reading your story though!

Trail cycling sounds like a good idea for you, maybe even on an eBike, depending on how strong you are. Falling on pavement or getting hit by a car is no joke, but even less so at age 87! Do a Google Search for "rail trails in Bucks County, PA". I had some interesting links come up.

We have one cyclist in my club who just turned 83. He got himself a hybrid eBike a couple years ago and hasn't ridden his gravel bike since.
