Elevated Tank Mega Post

Water tanks (and a few grain elevators thrown in) from our travels! This post is dedicated to one of our young engineering friends to has a mild obsession with "elevated tanks". You know who you are. For everyone else, feel free to take as much or as little away from this as you want. There will be no commentary, because like most of you I know nothing about the subject matter, but feel free to comment with your own.
