A little shake was all I felt ,we get these tremors when I live every year or so. Alot of lot of non Californians get scared pretty bad from the tremors I have heard. Strangely, I had an earthquake dream before it happened so I woke up a few minutes before. The south bay area is pretty far from Napa valley thank goodness so nothing too big could be felt from here. I do feel bad for thoes that live closer as I heard there was a lot a damage. I really need to get an emergency kit before one hits here again (similar to the '89 the 1908 quake.)
