Did you know you can dig a huge hole in Lincoln Park without a permit?

That’s just one of the revelations that came out of Friday’s opening hearing in the lawsuit filed by the Committee to Keep Lincoln Park Public, a group of north-side residents looking to keep the Latin School from building a soccer field just east of the zoo.

The residents say there are many reasons to oppose the soccer field deal the Park District struck with Latin back in October 2006. But on Friday they asked Cook County Circuit Court judge Dorothy Kirie Kinnaird to issue a temporary restraining order to block further construction on the grounds that the Park District never got a building permit to construct the field.
