Did you feel it? 4.2 on the Richter Scale and you didn't feel it?!?!
Maybe it's because you were this side of the bridge. The epicenter was one mile northeast of Lafayette.
They felt it in Rockridge, and here's the proof, via the security camera at Rockridge Home.
We were hanging a 7 foot curtain rod, and are a half mile from the epicenter. Threw us native Californians for a loop!
