i live in grizzly flats [California]. the strange booms and ground shaking really puzzle me, because I lived very close to shall we say… goverment bases, so i am very aware of sonic booms and their effects on houses etc. as well as major earthquakes. something very stange is happening here, I hope it is nothing dangerous or sinister. just be aware….
We are aware and watching.
