The last time I visited a theme park (many years ago), while wandering through the park I came upon this large sign. It was a map of the park with an arrow pointing to the spot where I was standing. In large letters the sign said "You Are Here". At first I looked for cameras and wondered why they were spying on me. Then it dawned on me that in order to get the sign painted and erected they had to have had advance knowledge that I was going to be there. This was before GPS and drones like they have today. Scary!
