The Shakes!

Tracy and I had the opportunity yesterday, October 21, to experience our first California earthquake.  Apparently a quake hit San Francisco that afternoon with a level of 4.0 but we didn't notice where we were in Walnut Creek.  But in the evening we felt a 1.0 in our area.  It only lasted a few seconds but was interesting to see things shake and doors shut on their own with no help from us.
