I'm actually starting to condition my voice now. I'm in sales and can't afford to lose my voice anymore. I just about went hungry after the first few games last year.
I'm with you brother, I can appreciate this. Have had season tickets since the early 70's. Older I got the longer it took my voice to recuperate. Try taking an old fashioned "megaphone". Maximum volume, minimum strain on the vocal chords. Even the small ones work. I have a full size one painted orange and decorated with decals. Use a Tennessee dog leash as a carrying strap. Have an email from Blackburn saying the SEC office allows them and for me to show the Gestapo at the gates. They tried to keep me out on several occasions when the "Cow Bell" thing was going on, till I flashed them the email and they still tried to call Blackburn on their walkie-talkie.
Maybe they should start handing out the small megaphones to all the fans? My wife has a small plastic one they handed out at the local High School games.
As some other posters have insinuated, not all of us "old folks" sit on our hands. And I have never been told to sit down in all my years @ Neyland.
