Found a hidden layer count in a 1990s municipal sewer plan

I was scanning some old paper drawings from a city archive and saw a note about a 'survey control layer' I'd never heard of. It was a full set of buried markers the original drafters put in, but no one uses them now. Has anyone else run into forgotten data like that in old files?

Ever find a note in your own files you can't even read? I'm my own forgotten data.

Found a sticky note from last year that just says "call about the green thing." No name, no number, just a green thing. My own handwriting looks like a doctor wrote it after three cups of coffee. It's not forgotten data, it's gibberish I created while my brain was elsewhere.

Man that's a good one. It's funny how we leave these little time capsules for ourselves and then can't even crack the code. I've got a whole drawer of napkins and scrap paper with what looks like ancient runes on them from my own hand. Half the time I think future me must have been a different person entirely, like some stranger snuck in and doodled cryptic messages. It really makes you wonder how much of our own lives we just forget and never recover.
