THAT THING ABOUT THE CITY OF HOUSTON AND DIGITAL BILLBOARDS A reader with “nothing better to do today” writes in with a question for Swamplot readers: “I do not see any digital billboards in Houston city limits. I see them popping up in Baytown and I’m sure elsewhere, but why not H-Town? One would think that this would be a win-win for the owners of the billboards and the businesses wanting to advertise their product. I see them all over Dallas — Houston, not so much.” Photo: Houston Public Media
