They are hard at it right now. Cops are investigating a Silver Spring MD couple who allowed their grade school age children to walk home alone from a park, about one mile. Fox has a couple of lady commentators raving about how terrible this was, it's cold, a mile is too far. Yackety Yack.
When I was in grade school we all walked home after school. It was a mile. No school buses in that town. I walked that mile to school and back from school, every day, rain or shine. That was in Saxonville, a medium tough working class town. This was Silver Spring MD, a silver spoon bedroom community.
