Most of my friends in the D/FW area didn't seem to notice anything. I'm not sure if it's that we live on the second floor and most of them (I think?) live on ground level, or if it's the location, since I'm probably more north than most of them. Not sure. Just took me by surprise.

Yeah, it's so weird to discover things like that. I'm not too surprised to see that earthquakes happen in places like that, but still... I mostly worry about tornadoes, you know?
