Just an update. Even though the I-5 was closed this morning, we decided to head back down to San Diego from Bakersfield. The drive went great with no delays and we passed the Horno fire burning near Camp Pendleton, getting some pics (hopefully I can post later).
Upon reaching home, everything was much better than when we left early Monday morning. Most of the smoke had cleared and you could actually tell that the sky was blue. There was some small debris blown into our yard and the front sidewalk is caked with dirt, but everything is just peachy.
Thanks to everyone who IM'd or emailed to check up on us!
