Well, maybe you don't, but several Friends of Unfair Park were curious why the Dallas Police Department sent out the vague message that starting at 9 this morning, "there will be street and sidewalk closures at 2014 Main Street [and] both Main and Commerce streets and sidewalks could be coned and barricaded off most of the day." Turns out, it's no big deal: Crews are removing an old fire ladder from the roof of the city courts building, and DPD didn't want it to come tumbling down on passers-by's heads or cars. So happened Anna was down there this morning and sends this heads-up.
