We stayed at Whitney Portal campground 7/25-7/27 and there was a bear every night. People did not realize they should not cook after sunset, even if the sky is still light.
At one point the bear pushed the campers out of the way so he could feast on everything in there open locker on on their table. When they tried to close the locker, he charged them.
As far as I know, nobody actually came into contact with him.
Cook your food early...that bacon smell at night carries a long way.
We had no food in our camp, but camp sites on both sides of us got hit.
