Who is this guy I see every day walking up and down Vance Jackson between Heubner and DeDeZavala? He's an older guy, has that "mental patient" look; he constantly, almost continuously, thrusts his finger or fist out at people in an angry, aggressive manner and angrily verbalizes something (I can't hear it in the car). If you've seen him, you know who I'm talking about. He's out there every day from dawn to dusk. Today he was gesturing at a woman walking 2 toddlers, and it was obvious she was very frightened. Who the heck is this guy?
