Certainly Not! I'd get one of those new (almost more camera than smart phone) gadgets and take all the photos I wanted during regular daylight hours. Besides which it is not illegal to stand on the sidewalk and take photos. So take that idiots at an un-named bank in downtown Denver. Because by the time you came out I was already done (and so was the rest of the class).
And never mind that you are already in Google Street View......It's the tallest building in Denver, prominent in any skyline view you may have seen, like these.
