A person locally tried photographing Electrical Towers and was promptly arrested and tossed in prison, the Police told him it was illegal, and when he disagreed, they arrested him.
Later, the city paid out $$$ to settle a lawsuit, but he still has a arrest record, and even worse, the Mayor of the small town is defending the arrest and it sounds like he would support doing it again.
Photographing anything that's "critical infrastructure" will probably get you hassled, despite the fact it's completely legal. With the obvious caveat that where you are standing at the time is somewhere you are legally allowed to be; either public property, or private property you own or are otherwise authorized to be on.
I was photographing a dam late at night with a couple friends. When we were leaving and got back in the car, five undercover cops boxed in the car. When they saw the camera equipment, they became very on edge to the point that they ran our license plate, our drivers licences and asked about the photographs we were taking. Ever since 9/11, the cops don't mess around.
Now when I photograph "critical infrastructure" and a cop stops me, I do not argue with them (unless they ask me to delete my photos, which I refuse to do). My advice would be to read up on felony vs misdemeanor trespassing and the laws regarding photographing such things.
I have been stopped over 30 times by the police for photographing somewhere I shouldn't be or something they regard as "critical Infrastructure". I have evaded any trespassing ticket and I have been only "warned" by the police a couple of times. If the police determine you to not be a threat, they will 95% of the time ask you to just leave.
