Have you ever visited a landmark just to realize later that, in fact, you did not?
I was hiking a popular destination in my town when I saw some tourists taking pictures in a certain place, congratulating themselves. After chatting with them, I realized that they thought they were at the end of the trail, but they were not. Had I not told them about it, they would have gone home thinking they had enjoyed the great views, when those great views were some distance ahead.
Has this happened to you? Have you visited a place, gone home and then realized you visited something else?
