We went camping a couple of weeks ago. The campsite was about an hour and a half east of San Diego, but the elevation was 4000 feet. When we arrived, we were quite surprised to find that it had SNOWED 6 inches the night before! We didn't expect snow in southern california in April or at all! Despite the cold we had a great time. Luckily we were mostly prepared for chilly weather. My toes were cold all night, but Matt and Madeline slept great.
