The 'Mining Barons' in Riverside County, California have "holed up for decades in the soft hills above Interstate 15, dynamiting hundreds of acres to extract the raw ingredients of concrete, roof tile and asphalt for construction across Southern California."
However, as growth has pushed outwards, housing developments are being built adjacent to mining operations -- and in some cases, literally across the street:
"We have the heaviest industry land use on Earth right here mining," he grumbled. "Then they go and put the most sensitive land use on Earth right over the fence -- senior citizen housing. They call that planning!"
