The last time a Park District advisory council weighed in on the Olympics, it didn’t come down on the side Mayor Daley wanted. That was back in July, when the Jackson Park Advisory Council passed a resolution against the city’s proposal to build a temporary 20,000-seat field hockey arena in the south lakefront park, part of its bid for the 2016 Olympics.

Well, this oughta teach ’em a lesson: In February Park District superintendent Tim Mitchell introduced a draft of revised guidelines that would impose stiff new conditions for membership in local park advisory councils, including criminal background checks. They’ve been sent to several advisory councils for review, but the Park District itself has the final decision.
