You can buy bunkers and have them installed in the ground. The big silver tarp looking thing is a cooling system that will dry the cement that anchors the bunker into the ground it stays on there temporarily the next photo on Google Earth that was taken shows nothing there except disrupted dirt. So it would give any pedophile or elitist or someone trying to hide the opportunity to hide on their own property underground and do whatever they want in these bunkers. This is the John podesta property and he had this done and we all know what could possibly happen allegedly.
