Thanks for the comments, and related tales - at least it helps to know we are a special bunch! Reply for the USPS is already in, boy that was quick - they just suggested that I contact the local Postmaster and see what THEIR policy is on photographing the building. Leads me to believe that 1. there is no law that prohibits taking photos of government buildings 2. the local postmaster is allowed to make the call..which again means it not law (unless they can get the local city/county/state to pass an something).
Appreciate the input, sure hate to see this..it just means that the terrorist have managed to not disrupt normal activities (like photography), but have managed to make some folks way to paranoid. Sigh!!
