KTLK put up a couple of billboards along I-394 on the St. Louis Park side. They show a picture of Rush Limbaugh, with the words "Big Talker. Big Station." and the station logo.
Both have been hit with what I'll guess were paint balloons. They were aiming for Rush's head, but got him in the necktie with butterscotch colored splats.
I also saw the same vandalism on the billboard off Hwy 35W, just south of Downtown Mpls.
Like you said: Typical.
