We in So. Cal. are blessed with weather year-round that makes the rest of the U.S. (except for Hawaii) envious. You can go skiing in the mountains and swimming at the beach in the same day.
But we have earthquakes! There is something in the air or the temperature that other Angelenos will attest to - we know when it is earthquake weather. Usually when it goes from being cool to super hot overnight, that is earthquake weather. And today was definitely earthquake weather.
So guess what? We just had one. 4.4 magnitude. Enough to get me out of bed and running for the doorway. (Although, they say now doorways aren't the safest place during an earthquake)
They also say pets are able to sense earthquakes and the smart ones give warning to their owners. No such luck here. Both Charlie and Chester cat didn't even wake up until they saw me running for the doorway. And they just yawned and went back to sleep.
