Having been around for a few decades and having been to more than a few Vols games at Neyland and elsewhere, I can say that by and large, Tennessee fans are good-natured, affable, humble, generous, and easily parted from their money with little remorse. This has been affirmed by numerous fans of other schools' teams, merchants, and members of chambers of commerce. I've heard more "Y'all come back, now. Ya hear?"s and "Your hospitality was awesome"s than stories of misbehavior by miscreants and misquided fans under the influence.
If your a Big Orange fan, be the person you hope to encounter. Live it. If you're not there yet, strive for it. If you see bad behavior by a fellow Vols fan, gently ask them to correct their behavior. If you encounter a victim of bad behavior, express concern for their welfare and offer assistance.
If you're just a swingin' Richard dedicated to behaving badly, stay home and watch the games on television. Otherwise, know that should I witness you behaving in a manner which merits intervention by security or the authorities, I will not hesitate to bear witness and see you enjoy the consequences of your transgressions.
Fandom should be good fun. GBO.
