Badwriting, you obviously don't understand school districts and their position when it comes to liability.
If you work in any administrative position for ANY company you would understand. In today's times many people have become "sue" happy and will sue anyone for anything!
The district has the obligation to protect itself and taxpayers from litigation. If the district is aware that having kids run on city streets unsupervised/supervised is a liability then it needs to take action to avoid losing precious taxpayer money to vicious parents who are willing to sue a school district if "bobby" twists his ankle on a curb.
I remember running in high school many times on city streets and I once was "honked" at and turned my head for one second and triped on a uneven curb and slammed to the concrete. I "could" have sued my district on grounds that I was unsupervised and was "told" to run on streets that were unsafe. Because I am apart of the school during team practices, I am still under the schools insurance and their liability.
Parents cannot sign their children's rights away when it comes to safety. Even though many of the waivers do ask this of parents, they don't hold water in courts.
XC probably is one of the few sports that has liabilities beyond the confines and supervision of the basketball courts, baseball fields, and swimming pools most American sports are use to.
I am not surprised that a district would take a stand on this issue since its always been a grey area. I would be surprised if they one day confine XC high school runners to only the track. That would be a sad day for running when my high school son has to do a 12 mile run on the track on a Tuesday afternoon.
The only way to combat this is to teach children road safety, hold team meetings where you spend an hour each month teaching road safety, then have multiple volunteers follow small groups of runners on the city streets to remind the students of these rules while monitoring them.
Its the times we live in. I taught special ed for many years and parents there are always looking for ways to get districts to pay for "everything" at the expense of other taxpayers. Its sad because lawyers have such a deep hand in the everything nowadays that you have to protect yourself from sue-happy people.
I don't even allow friends on my property who I don't know for reasons that I am liable if they trip on my side walk or jam their finger in a door way.
