There is a natural spring near my house that I have never been to. Apparently in pioneer-ish days a family named Chenault lived here, and they relied on this spring to provide water for themselves and their horses and possibly for gardens. There were signs that a garden of some sort was once there, bulbs probably of iris coming up in a neat row in the wilds.
We come across a homeless camp near the spring and study the things they left behind - apparently there was a fire at some point and that might have been what drove them off. We check out the spring, the water from which was once retained behind a brick wall, and measure the flow. The spring may be threatened by development in the area, it remains to be seen how much, but in any case we got to explore it in all its muddy glory.
