These earthquakes are disturbing. When I worked for Perko’s in the ’70s, I worked in the bay area and I got the misfortune of going through a series of them. One night just as I was going to bed an aftershock hit and without any other noise to cover up its sounds I found it to be the most frightening thing I have ever experienced.
If you search online you can listen to earthquakes from all over the world. However, I find none of these sounds as frightening as being in the same house as my son when he is beating on his newest drum set. After realizing how I messed up last week I bought my son a kid set, but my WIFE went out and got him a FULL-SIZE drum set with all the attachments. If I had a choice I would take the fear of earthquakes over the total insanity of drums.
