See also the Forestiere Underground Gardens in Fresno, dug by one man over a period of 40 years from 1906 to his death in 1946. He came to Fresno from Sicily and when he couldn't productively grow citrus on his property, he began digging. The tunnels are nice and cool in the hot Fresno summers and there are fruit trees growing in open-air sections. They give tours. http://www.undergroundgardens.com/ http://www.undergroundgardens.com/ https://en.wikipedia.org/wiki/Forestiere_Underground_Gardens https://en.wikipedia.org/wiki/Forestiere_Underground_Gardens
