A lot of the fans that sit here have been coming to Cubs games for years, so they're very knowledgeable about both the Cubs and the game. If you're a fan of the visiting team, these seats would be the most ideal for you since they're behind the visiting team's dugout. If you want autographs from the visiting team, slide on over to section 33 before the game. Beware of the ushers though; I would have to say they're among the most unfriendly in Major League Baseball and I've seen baseball in a lot of ballparks.
A lot of people see the rooftops across the sreet on WGN and want to sit there. Take it from me, it's not worth it. You want to be actually INSIDE the ballpark.
The Cubs fans are friendly as long as you're respectful and don't try to cause a scene.
