I remember my little sister telling me before the tour that we needed to stay in front of the tour group to get the best shots (with nobody in front of us). She really did her research that day. So throughout the tour, we stayed in front...my sister would tell me where to get a shot , then she would get her shot. I had a childhood like moment, when all I can think about was NASCAR. Yes, NASCAR...where you race to the front of the pack of cars and make sure the group is behind you. Anyway...once we got our shots, we would get out of the way for the folks behind us to get theirs. In the famous words of Ricky Bobby: "If you ain't first, you're last".
