MADISON, WI—Graduate student Danny Lindner, 26, reported that he was shocked Monday to see a guy just totally smoking pot right on the street. "This dude was, like, just walking down the sidewalk puffing on a joint, right out in the open," Lindner told roommate Kyle Rath. "I could totally smell it. It was so weird. What was he thinking?" Lindner added that it was broad daylight out.
