Baltimore's Arena Football League team has sold 500 season tickets for its inaugural season, but owner Ted Leonsis said it's way too early to be concerned. "I ask that you have a little patience with us. Let's have some fun together," Leonsis said during a speech Wednesday to the CEO Club of Baltimore. "We've sold like 500 season tickets. I think the arena seats like 10,000 people." The Brigade open their season April 7 against the Washington Valor. The Brigade, who will play at Royal Farms Arena, have been selling about 30 season tickets a week, according to Jeffrey Bowler, vice president for business operations at Monumental. Bowler said that pace does not concern him, given that the team has only recently begun its marketing. The team doesn't even have helmets yet, Leonsis said. "There is still three-quarters of the city that doesn't know this is happening," Bowler said.
