This is another picture from Christoval, Texas around 1900. The picture shows men using horses to build a dam across the South Concho River. It is interesting that I can recognize this exact spot today, and it is just a couple blocks from my house. The area the men are standing is where the highway crosses the river today. The big tree on the left is still standing.
Later, the river area shown in the background became "Playland Park", where you could swim, rent paddle boats or canoes, fish, or just have a good time. Where the big tree is, there was a rope bridge which you could use to walk from one side of the river to the other. Playland Park pretty much shut down in the 1980's as kids became more interested in TV and video games than in fun days outside.
