I just went to bed last night and 5 mins later I'm swinging side to side. I was about 5 miles from the epicenter of a 4.5 here in N. California. Two mins later another one of 3.9 hits.
For me, it's a small one that gets your attention, but not enough for me to get out of my hammock. I've been in 2 really big ones, with the last one being the 1994 Northridge earthquake in S. California. I broke all types of speed records with that one.
