BALTIMORE - As vans and trucks pull into parking lot O at M&T Bank Stadium, they are sure to see the familiar face of Matt Andrews, more commonly known as "Fan Man."

Andrews and his three friends, all with Ravens aliases like Andrews, make up the Bus Boys, who attend nearly every home game from Harford County. Andrews owns the bus, which has been painted purple and is filled with Ravens and Colts bobble heads and other paraphernalia. The sides of the bus spell Baltimore the proper way, Andrews said, pointing at the sign painted "Bawlmer Ravens."

Andrews has a particular rivalry with his family during the Ravens and Steelers game, he said. Andrews is originally from McKeesport, Pa., about 10 miles outside of Pittsburgh, and moved to the area in the 1960's for a job. He became a Baltimore Colts fan before he moved, he explained, because of his uncle.

The headboard of the bus has a photo of Andrews' uncle, William Andrews, who was the ultimate Baltimore Colts fan, he said. When his uncle died, several players from the Colts were pallbearers at the funeral, he said.

"I've got this naturally in me," Andrews said.

In 2000, Andrews was chosen as a VISA Ultimate Fan, and is recognized in the National Football League's Hall of Fame. In 1998, Andrews said he began fanning, and bought his bus 12 years ago.

"In 2000, I went into the Hall of Fame with all the other crazies and I've been doing this ever since," Andrews said.

Andrews is well known by Ravens players and fans alike. His friends, whose larger-than-life photo lines the back of the bus, attend nearly every game with him. Sunday, John Dongarra, also known as "Camo Man" and Rick Dixon otherwise known as "Ravin' Rick," prepared for the game with food and music. Also shown in the life-size photo is Dale Davis, also known as "Maniac," who wasn't able to make it to the game, Andrews said.

The men have helmets and hats, as well as come to every game with their faces painted. Each of the four men has a case for the 40 pounds of beaded necklaces they wear to each Ravens home game.

As the Bus Boys partook in their usual Sunday routine, another fan, Steve Timchula, decked out in purple military gear, walked by to say hello. Timchula, from Westminster, became known as "Major Offense" in 2011.

"He got promoted right in this lot last year," Andrews said.

Timulcha puts on his purple military uniform for each home game, which is lined with Baltimore medals. The medals and stripes look like replicas of military medals, which are made every year that the Ravens make it to the playoffs, he said. Timchula, who comes from a military family, and was in the National Guard, said his friend makes the medals for him.

Timchula explained in 2008, he became Captain Offense, after Joe Flacco and Rice were signed to the Ravens. He has both a helmet and a sign on the side of his purple van which says "Offensive HQ."

Even though this year the Steelers have suffered injuries that have set back their season, the rivalry between the Steelers and Ravens is alive and well, Timchula said.

"It's always going to be strong," Timchula said. "Now, after we slaughter them about 17 times, maybe it'll go away."

Despite a vicious rivalry, Andrews said fans are fans, and he's never had a problem with any fans from opposing teams. With the Steelers, a win would mean the Ravens could start looking at the playoffs, Andrews said. The rivalry mostly just means a dislike for the other team.

"The whole team dislikes each other man to man, offense, defense, division," Andrews said.
