If ever there was a perfect example of this lesson, this was it.
To Lead - travel in front of; go in advance of others or to take somebody somewhere.
To Follow - to travel behind, go after, come after
If you're not going to do either of these two things, then please...just stay out of the way - The OSU drum major was doing his job leading, the OSU Sousaphone player was doing his job and following...The cameraman? Not sure what he was doing, but he paid the price for it. So like I said "Lead, follow, or get out of the way" - or you're bound to get clocked on the head!
