I grew up in a more rural area east of San Diego. Very free roam. Kids were spread out but we could bike to each other's houses. A couple of kids at my elementary school died. One in a cave-in of a small cave some friends dug in the side of a cliff. Another when he went for a ride in the 4WD of a teenager that flipped over on a hillside. I wonder what the fatality rate was in the old days versus these days.
