installing conduit for FIOS. All were Hispanic, working for a contractor. They dug a rectangular hole at each house, as well as additional ones in between where the runs were too long.. After a horizontal "mole" driven by compressed air created a horizontal tunnel,they pulled the heavy conduit through it.

I am amazed at how hard these guys work, digging in red clay with long handle shovels. After they installed the boxes that will contain the interface for each customer, the carefully tamped the soil, and replaced the sod that they had set aside, finally seeding the disturbed areas and putting down straw. I doubt that you can find a crew of "gringos" would will work as hard as these guys do.
