And the crew could hardly walk 10 steps without someone stopping them and asking to take a picture. They never refused, and they never toned down their enthusiasm. Even as the day wound down, and most of them had been up for 12 hours, Fan Man was still dancing in front of the bus.

The evolution of Fan Man

Fan Man is from Pittsburgh and moved to the Baltimore area in 1965 with his wife. Then a teacher, and trying to start a family, Andrews was unable to invest the time and money into football super fandom with Baltimore's then-team, the Colts. But he was still a big fan.

"We still love our Colts," he said. "When they left, it was heartbreaking. It just ripped the heart right out of your body."

And for 13 years, after the Colts snuck off in the night to Indianapolis in 1984, Andrews wandered from team to team. Being a Pittsburgh native who left and rooted for the Colts, he wouldn't go back to being a Steeler fan; he rooted for the Washington Redskins for a while, but never with the same fervor.

"There was no dying love for any one team," he said. "If I missed a game, an NFL game on Sunday, so what?"

Then the Baltimore Ravens came, breathing life into Baltimore's football lovers, and especially into Andrews.

At first, says Andrews' daughter, Tressa, she and her mother were concerned that he might be taking it too far.

"He might've lost his mind," Tressa said, remembering when her father created the Fan Man. "But I knew why he started it, so I was really excited that he got the chance to actually venture out and do things he's probably been wanting to do for a while."

The Andrews' family has a tradition of super football fans: Matt is the nephew of Baltimore Colts super fan Willie the Rooter, to whom he has a sign paying homage above the driver's seat in his fan bus. The sign is covered with small football stickers with Baltimore Colts players' names – and they're all signed by the players.

Andrews says Willie was loved by both players and fans, and that inspired him.

"He was that kind of guy, he went the extra mile," he said. "And we all do remember - I remember him forever and ever."

And Tressa Andrews said she'll be glad to continue the family tradition when her father is no longer the Fan Man. (She and some of the Bus Boys agree that he won't retire his Fan Man helmet and feathered jacket while he's alive.)

It's in Andrews' will that he be cremated and his ashes placed in the back of the fan bus.

And that those attending his funeral will be encouraged to tailgate.
