Tension filled the air at 7th and Montana this morning as a dead ringer for Charles Manson made the scene ... and the resemblance was more than just physical. According to inside sources, he arrived at 5:30 a.m. and almost immediately began raising a ruckus, throwing chairs and umbrellas on the sidewalk. At 6:30 he enjoyed a cup of tea, following which -- renewed and refreshed -- he began pacing up and down 7th Street like a caged animal. By 9:30, he was back to throwing things around and cackling like a hyena, albeit this time under Police Surveillance. Two squad cars arrived and a group of police officers watched his every move for about 30-minutes. At one point, they told him to calm down, but it didn't work. After the police left, he started pulling branches off trees, kicking furniture, knocking down signs and frolicking in the middle of the street. The only thing that seemed to calm him down was the arrival of Lucky, the Wonder Dog. "I know this dog," he said, "I kidnapped him 25 years ago. I wanted to kill him but he got away." Lucky wisely fled the scene. As for Mr. Manson, he took off shortly thereafter, leaving a Helter Skelter pile of chairs, branches and umbrellas in his wake ...!
