Dave, not sure if I should post this but here goes. Before I retired I worked for the sixth largest School District in California, Maybe it was just Southern California. The school principles got together with the school board and decided not to allow bicycles on campus. They used safety and security as their reasoning. What ever the reasoning it eliminated more 80,000 students from the potential cycling pool during the school year.
They then tacked a $300.00 bus fee per student for my son's high school and that led to more kids driving and lines of cars in front of all the schools dropping off and picking up their children.
I have moved but even now if you go into town about 2:30 pm you know to avoid any street with a school on it.
