I can't remember now) -- I was getting coffee in the break room and when I got back my co-workers were like, "did you feel the earthquake?" "What earthquake?" "The one that just hit a few minutes ago." "Nooooo...?" It wasn't until later in the day that I was sure they weren't kidding me.
Is that the one with the epicenter in Virginia? The quake that damaged the Washington Monument? I was taking a nap when it hit, and apparently my mattress did a real good job of transmitting the vibrations. I think it woke me up. I definitely notieced it.
@classicdrogn Maybe it's a resonance thing. That's been an issue with certain bridges and much more recently than Galloping Gertie.
