Never had a problem at any Cardinal games, however some fans got out of control at Mizzou/Kansas game at Arrowhead. A lot of cursing and baiting (not good natured ribbing) the other teams fans. I must admit my son was probably one of the worse (the kid could never drink and doesn't know when to stop) and embarrassed me to no end. However, at 25 I couldn't very well spank him front of the crowd, but boy did I want to. Overall, I say I've not witness that much at the Rams, Blues or Cardinal games throughout the years and I probably attend maybe 40 games between the three.
I went to see the first-ever game at Ravens Stadium (can't be bothered to remember who bought the naming rights, and even if I could, I wouldn't want to give them free advertising). We took a booze bus from a bar called The Judge's Bench in Ellicott City, and my buddy and I instigated a beer-can shotgun competition (judged on speed, overall quantity, and grace) which I of course won. My buddy tackled me down the bus steps and onto the pavement of the Pigtown parking lot, and while the rest of the bus tailgated, he and I wrestled, giggled, and popped one another in the head with full beer cans. By the time we got to the game, we were loaded, half-concussed, and ready for a snooze, which the Ravens obliginly gave us in the form of a 3-0 victory. I don't remember who they beat. The game was so dull that I never even thought of swearing at the top of my voice or pouring my beer cup, emptied and refilled with urine, on the usher. I learned foul language as a kid going to Memorial Stadium to see the Orioles: a row of big-bellied men with a big cooler filled with beer (not cans or bottles, just beer sloshing around inside. They sidestepped the ballpark container laws, using the spigot to pour increasingly flat beer into dixie cups they brought from home) sat a few rows behind us (Section 39, Row 11 or 12) and used language colorful enough to fire my preadolescent imagination. I went to a friendly soccer game at RFK a few years ago between DC United and Newcastle United, and, finding myself standing next to an Englishman during the national anthems, belted out "My Country, 'Tis of Thee" over "God Save The Queen." His jaw dropped, so I winked and said, "We mean it, man!" and then asked him if he thought we'd see Shearer play. When the first Tynesider took a dive, rolling around in his black and white stripes clutching a phantom sprain, my brother stood up and shouted, "Go back to Footlocker!" I bring this up not to say that any one sport sponsors more or less foul-mouthed, coarse, or violent fan behavior than any other, but to illustrate the difference in behavior at games we care about or that matter in the standings from behavior at friendlies or laughers or novelty matches. And also to show how much fun it can be to come up with taunts and ribs that aren't obscene or threatening. Though those stevedores in Section 39 really taught me quite a bit about proper swearing, for which I thank the fat limpdick ratfuck bums. Violence is another thing: absolutely unacceptable.
