The other day I stopped on a public street near a private firm that does locomotive repairs and has a number of engines parked out of doors. While I composed my shot with a long lens a private security guard drove out to the street and asked me not to take any pictures. I questioned his requests and he told me that his bosses have been instructed to chase any photogs away no matter what. The guy was nice about it so I did what he asked. At no time was I on or near the private property but did aim a camera at it. IS THIS ILLEGAL?? DID I ENTER THE PRIVATE PROPERTY WITH MY EYE THROUGH THE LENS?? IS THIS PRIVATE FIRM TRYING TO HIDE SOMETHING FROM THE FEDS?? COULD A HOBBY BE CONSIDERED CORPORATE SPYING?? I think I'm getting paranoid.......
