Heavy Chemtrail Spraying - Orange County, CA

I spent a lot of time outside on Sunday 1-29-12 (in Orange County CA), from about 9am to 4pm.  (Multiple pictures below). I could NOT believe all the spraying that was going on. Why does it seem like they are stepping up efforts? Is there something currently happening that requires heavier spraying?
