When the Martinez family settled, it was for good.

Since the 1980s, several brothers from Ciudad Altamirano in the Mexican state of Guerrero picked oranges in Florida, harvested onions in Georgia and worked tobacco in North Carolina.

After they got green cards in the early 1990s, they decided to stop moving. They brought their families together, rented a group of single-wide mobile homes in Columbus County and took permanent jobs at construction sites, factories and a golf course.
