The Chicago White Sox do not let fans access the main concourse level without a ticket for a seat on that level as it is one of the few parks in Major League Baseball that do not allow fans sitting in the upper deck to venture anywhere else in the park. Basically, any fans in the upper deck seats cannot enjoy the amenities available on the main concourse because they cannot afford to buy the expensive seats!  This wasn't always the case, in 2002 a father and son contended they were provoked before bursting onto the field at a baseball game and attacking the first base coach of the Kansas City Royals.  Ever since this incident the ballpark and organization changed who it allows on the main concourse.  I believe this is prejudiced and unfair treatment of the fans who cannot afford to buy lower level seats for a baseball game.  I want my sons to enjoy the same excitement I had attending White Sox games growing up in Chicago!  I have never been to another stadium with such an outrageous rule. Please help make a change so all fans can enjoy all amenities at U.S. Cellular Field for the White Sox!
