because some jack-ass decided that even though it's one of the hottest, windiest, driest times of the year, to go ahead and burn his leaves. So now a ton of people have to evacuate their homes.
Don't be stupid.
UPDATE: More than a dozen homes have been burned and Cal State San Marcos is on fire. There's firefighters from Riverside that drove in to help.
Also, it sounds like they rescued the animal shelters as well as animals in the homes.
