Earthquake!

We just experience our first earthquake. It was a 5.8 with the epicenter of Chino Hills (just slightly south and east of us). Zoey started running up and down the hallway and when I walked out to check on her I realized that shaking and noise was not just a large truck rolling by our house. The shaking didn't really last very long, but it was definitely serious shaking. Totally freaky. Apparantly aftershocks can happen up to a week after the quake, so we have that to look forward to.
