I don’t know the construction workers name. The picture was shot from over the fence. Honestly I couldn’t even see what I was shooting at. So the photos I took where a surprise to me when I finally saw them. Because I hadn’t been able to see what was captured that day at the zoo. I didn’t make mention of this in the other article. But it looks as if a well driller is being used in the top right corner of the picture. This might be the early stages of building for the geothermal system. In my other construction photo there was another view of this same piece of equipment.
