Bud kept walking until he was a little too close to the guy. He kept his 
head tilted back until the last minute, like he was kicking back listening to 
some loud tunes (which he was), and then suddenly snapped his head forward so 
he was staring the guy right in the face. It was another way to emphasize the 
fact that he was packing, and it usually did the trick. But this guy did not 
respond with the little flinch that Bud had come to expect and enjoy. Maybe he 
was from some booga-booga country where they didn't know about skull guns.
