Last week I was in Pittsburgh!! We lived there for a few years and what I remember of the town was a poor road system and lots of snow! This conference showed me the other side of the town both downtown and slightly further out.
The first surprise was that the conference center had a garden on the roof. There were concrete beds filled with tomatoes, kales and other fresh vegetables which were harvested for the hotel or conference events.
And there were flowers too for pollination!
