Southern Idaho Earthquake?

Was that what I think it was?  Many people around southern Idaho, in the Magic Valley in particular, are reporting a possible small earth temblor that occurred sometime after 9 p.m.

Many people on Facebook are reporting feeling something.  Some say it was an earthquake, some say it was something from the Saylor Creek Bombing Range.  Others say it was "fracking."  No reports yet from the USGS earthquake map.

Did you feel anything?
