Beekeeping and Green Roofs in Chicago

This may just qualify as shameless promotion of both my city and our Co-op but I wanted to share a video on rooftop gardens that TF1 (French Television) broadcast last evening. You get a birds eye view of the rooftop garden on Chicago's City Hall and the beehives maintained by Chicago Honey Co-op head beekeeper Michael Thompson. He has been keeping bees since he was 12 years old living in Kansas. The bees atop City Hall here do exceptionally well and receive no chemical or antibiotic treatments. Chicago also has a rooftop garden on the Cultural Center here, also with healthy beehives.
Two other Chicago rooftop gardens are also featured.
