*Apr 29 - 00:05* Unlike the pretentious trustees of Gramercy Park, Aldon James, president of the National Arts Club, believes the exclusive 2-acre oasis should be open to the public. Currently, only key holding residents like himself can access Manhattan’s only private park, a rule that he likes to challenge. Although his latest protest was over recent temporary closures of the park for maintenance, he really upset the gatekeepers in 2001, when he did the unthinkable: He allowed 40 minority students in. |NYDN|
