A Friend of Unfair Park who's working hard for the city shoots us the following missive, concerning one of downtown Dallas' landmarks: "I just noticed, as I looked out my City Hall window, that the Mercantile Tower and clock is finished and operational. It is quite nice looking." R.L. Thornton would be pleased, no doubt. And news of the ticking clock did send me over to the Mercantile Place Web site -- apartments available from $1,325 to $6,650, how to choose. Also, there plenty of work-in-progress pics of the building to be found on Flickr. --Robert Wilonsky
