Everyone made nice at today’s formal announcement for Jackson Park as the location of the Obama presidential library.

This is the second recent loss of a world-class development project for Washington Park, which was also expected to be a prominent site for the ill-fated Chicago Olympics.  But if anybody was disappointed, it wasn’t showing. One speech after another emphasized the benefits the Obama center will bring to the south side and the entire city.

Behind the podium, waves rippled on the surface of the lagoon, ducklings bobbed, and, across the water, the calm green expanse of Jackson Park awaited its much-anticipated new occupant.
