But that's exactly what downtown Baltimore had Tuesday morning.
One Steelers fan showed up and she didn't slip past any Ravens fans. Wearing yellow and gold from head to toe, Ravens fan chanted "go home!" and "Steelers suck!" in her direction.
She took the criticism like a pro, though, sending trash talk back at the Ravens fans surrounding her. It didn't take long before she was chumming it up with Ravens fans around her.
If you're a Ravens fan, can you even have animosity? Your team just won a Super Bowl in fairly convincing fashion and your rival had a poor season, by their standards. The best way to deal with a Steelers fan is just laugh and tell them, "Maybe next year?"
The parade was scheduled to start at 10:45 a.m. ET, but it still hasn't started. The team is stuck in traffic, according to Will Brinson of CBS Sports.
