Rubin has been in the US legally for over 40 years. He and his family owns a storefront flower shop in the mostly Mexican immigrant Chicago neighborhood of Brighton Park. On weekends he sells roses at the end of an off-ramp of US Rt. 55 at California Ave. He’s got a rhythm about his work. Deftly timing the lights and drifting effortlessly between the oncoming traffic –much of which are cement trucks heading the the nearby factory. If you listen carefully, you can hear his whistling. He makes bird songs the entire time he’s out there.
