Off topic....but did anyone in Wyoming, South Dakota, Montana just feel a slight tremor about 9:10 MST? Our house shook. My son, half a mile away called...they felt it. Friends about three miles away called to ask if we felt it. Daughter in NE Wyoming called to see what was going on. No, we did not all share bean burritos tonight.
Dogs and cats certainly reacted, and they did not have burritos either. Nothing on the quake sheet yet. Earthquakes are rather rare here. Just curious.

Here's the last earthquake report (online at this moment) regarding Wyoming (exact quote from the 3rd link I sent you)
