Taken yesterday in Detroit Michigan, during a visit with a photobud who is doing a project on the Michigan Urban Farming Initiative, a program to grow food on unused plots of land within the city.
At one of the farm sites we visited, in addition to the fields of fruits and vegetables they have erected two greenhouses and currently have plans to put up a third.
Looking into one, I watched while one of the volunteers weeded the young crop, and took this shot.
