I have posted this before back in 2016. Someone I know, who I exchanged some information, asked me out of the blue where it was. I trade information with a very small group of people. I remembered the general vicinity of where it was, I just could not remember exactly where it was. I could not find the location in my notes anywhere. I messaged the person the area where it is. Last weekend it bothered me enough that I drove a bit over two hours from my home to confirm where it was, took a photo when I was there, and sent the person the location.
I really have to start taking better notes.
