we've had 2 earthquakes in the past 2 months-- both in the 2's (2.5 and 2.9--i think)

2s? Did you feel either of them? Anything less than 4.5 wouldn't even be noticed here, and I know people who have slept through 5s. My Dad was driving around town during our last signifcant shake, 6.4, and when he got home and was asked about the quake, he replied "what quake?"
