Rob and I were coming back from luch today and felt a little shimmy while I was driving and the bells at the railroad crossing were clanging away with no lights flashing, but we just thought it was a weird fluke. Once back at the office we found everyone standing in the parking lot looking surprised...
As it turns out there was a 5.4 earthquake which is enough to give a good ride, but not cause and serious dmage that I know of. The epicenter was but a few miles away in the Diamond Bar/Chino Hills area, for more info click here.
