To all budding photographers out there, I highly suggest buying Bert’s book on what your rights are ( in the US ) while taking photos.
His web site also has a PDF you can print out and keep with you in your bag for the inevitable interaction with LEOs.
My general recollection is in the US if you can see it, you can legally take a photo of it. The major exceptions are nuclear weapons bases where they will shoot first and ask questions later, highly restricted sites like Groom Lake, and taking photos of people in their own home-you enter into peeping laws there because even if the shades are open, they have a reasonable expectation of privacy in their domicile.
