It was fitting that a security guard challenged me for taking photos of this abandoned factory by asking if I was authorized. I was standing on the road at the time, so it was a short conversation in which I wasn't particularly helpful. It ended when he went to call his supervisor.
I left him to his radio and continued to do what I was doing. The guard's supervisor arrived with surprising promptness, and after they had a brief conference, he drove over to me to let me know that there was absolutely no problem with me photographing from the street.
I knew that already.
I suspect that I was the most interesting thing that happened on a rainy Sunday afternoon.
