Before the southwest Valley was filled with grocery stores, an airport and real estate, it was home to Latino farmworkers employed by Goodyear Farms. 
Hundreds lived in five different camps made up of tents and wood-framed houses.The tight-knit communities were the first permanent residents of what is now Litchfield Park. 
In this week's episode of Valley 101, a podcast from The Arizona Republic and azcentral.com, producer Maritza Dominguez walks us through the history of the Mexican laborers who were recruited to work in Arizona’s cotton industry, the campsite communities on Goodyear Farms and the Latino farmworkers' impact on the development of the southwest Valley.
