About ten miles up a fairly decent dirt road from US95, surrounded by the Kofa National Wildlife Refuge and the Yuma Proving Grounds, is the Castle Dome Mine Museum and ghost town. Some of it was brought in from old mines in the region, some of it is a recreation. All of it got me wondering about the type of people who would dig holes here looking for wealth. Or even just a subsistence living. Hard people. Driven people. Not people who blogged.
