Those TxDOT Cams Need Deicing

A Friend of Unfair Park who travels up and down Central Expressway all day long and uses the Texas Department of Transportation cams before heading out sends word: Many of them are completely useless today, courtesy the ice that has glazed over a few of the lenses. But, on the plus side, they're very, um, arty? And, besides, the ones that are working reveal fairly empty highways this on-and-off snowy afternoon. --Robert Wilonsky
