Thanks to TVSpy for linking to my KPRC 2 anchor Owen Conflenti planks on live TV post. The post also clued me into more planking activities at Houston TV stations (you know I only report on the serious issues that matter to you and your family).
As you see above, Mason Lankford of @folkfamily planked at the Fox 26 KRIV studios. Thanks to @GunsandTacos for that tip.
Apparently the first person to plank on Houston TV (on tape) was the Houston Press' Craig Hlavaty. It was on KIAH 39's Between the Lines segment for NewsFix.
