Bobby Dodd gets pretty darn loud. It's a hobby of mine to attend games at this great country's famed college football stadiums. I have been to multiple stadiums (most notably LSU's Death Valley) and Tech is not that much quieter than the rest. Now, LSU's Death Valley is in a class of its own compared to Tennessee, Alabama, Penn State, Ohio State, etc. They are the only stadium to register an earthquake via noise on the Richter scale. We will never get as loud as that stadium because they are on a different planet as far as crowd noise is considered. Read what Bear Bryant has to say about it:

We get loud when it counts. Especially when you see Michael Johnson waving his arms to pump up the crowd ... what a rush!
