Full disclosure: my new book Cliff May and the Modern Ranch House (Rizzoli) - this is Dan Gregory writing -- uses new and archival photography to showcase May's work. Realtors Doug and Rochelle Kramer share their expertise about Cliff May's tract ranch houses on their website
www.ranchostyle.com. Other ranch house resources are

www.eichlernetwork.com). Architects across the country adapted the suburban ranch house idea during the 1930s, 1940s, 1950s, and 1960s.
