No "school zones" around private schools here.
There are still areas throughout the country, on private and/or rural roads, where the local citizens refrain from calling the LEOs, and will just shoot at your tires for speeding down their roads. School zone or not.
Keep your cell phone handy, while you walk to get a signal.
Because chances are nobody nearby has a phone to let you call AAA...bless your heart.
Here in Houston there is no bus service or "walkers" to private schools as they are dropped off and picked up by passenger car.
