On one of my shops for them, the only place to get the perfect photos was directly across the street, and that wasn't going to happen because it was the entrance gate to a military base. I was not about to drive over there and say, "Hey, four guys with rifles, I need to park here for a minute and take pictures of the place across the street from your military base gate. Uh, for non-terrorist purposes, I swear."
I ended up having to loop through the intersection three times just to get a good photo of the front, and four more times to get enough photos of other elements.
