It was like a bad horror movie. There was no escape from the hordes of Van Halen zombies pillaging downtown Kansas City early Friday evening. Most of them looked exactly like me, except that they were visibly happier. I love Van Halen, too. I saw them at Kauffman stadium in '77 and I even have a favorite VH song. But I was downtown for another show, and I wasn't in the mood to watch goofy dudes play air guitar. I finally found refuge at Truman's, an odd little place inside the lobby of the former Kansas City Club.
