The Oak Fire started earlier today (Fri) between Modesto and Yosemite in Mariposa County.  It was first spotted when it was less than 40 acres.  In a very few hours it expanded to more than 4,000 acres.  CalFire is very much afraid that this could turn into a MegaFire very, very rapidly and are already looking at major evacuations in Mariposa County.  

Too bad all the fucking tree huggers here haven't managed to figure out that letting underbrush build up, refusing to remove dead trees and refusing to cut fire roads does not make the forest better.  In fact it has the opposite result.  It does, however, allow the assholes in charge feel morally superior.
