We (finally) were putting in the lights around our pool so we can use it at night. And we ran into ---- caliche. It's what they call dirt out here - more like concrete. So we had to go rent a jackhammer.... David seems good at it though.
It was really really sunny while we were doing the jackhammering. As you can see by the nice shadows we made. Note the hats - survival necessity out here.Final results of the lights - light in the pool too. We jumped right in.
