That was a weird experience … my first earthquake. 5.6 magnitude, centered 9 miles away, the whole hotel shook for about 15 seconds. At the Adobe building across the road, the lights must not be wired in very tightly, because lights were flashing on and off the whole time. OK, I guess it’s sort of like being on an airplane during turbulance.
