"There was concern that a lot of kids would change the complexion ... and the atmosphere of the club"
In post racial America we are again taught how truly equal everyone is. The The Creative Steps Day Camp paid the Valley Club for access to it's pool. They went to access this pool, only being told to leave because the membership to the club does not allow black people per the camp. The manager of the club said the quote above. Apparently they were worried about the "complexion" of the campers changing the atmosphere of the club.
Also note, this was not in the south, as there is a stereotype that we in the south are somehow more racist than our northern counterparts, but this was in Philadelphia. It doesn't matter where you live in this country, racism it seems cannot be avoided.
