I have done this for places I visited a lot in my early childhood but since have never returned to. It's a bit eerie to see the memories come back to life. Often I remember just enough of the place to be able to find my way between what were the main attractions to me at that age. Somehow, despite forgetting all the details of the path, something in the back of my head compels me to follow the right road even in confusing intersections. I find it fascinating.
