I rode a bus to school until my my last year at the University. In high school Dad dropped us off at the collection point on his way to work where we waited for forty minutes until the bus arrived. We dressed for the weather and put our coats in lockers at school.
Today, if you drive to town on a school day, one will see legions of minivans idling at the end of driveways. The minivans are filled with kids waiting for the bus. The van is idling to keep them warm.
If you are behind a bus, you see the kids hop out of the minivan wearing indoor clothing. It is not unusual to see a kid hop out of the vehicle wearing shorts, tee-shirt and Crocs, even in January.
After disgorging the kids, "mama" backs the van back up the drive to the garage or she then leaves for work.
This is what the majority of "country kids" in this zip-code are like.
The chances of most of those kids being able to walk three miles or be able to function outside for hours (cold in the winter, sun-mosquitoes-heat in the summer) is vanishingly close to zero.
