why is there not skateboarding at schools

Question
Good day,
My name is Ryan and I am working on a project for my Information Technology class.  I was hoping that you might help me.  My research question is: 搘hy isn't there skateboarding at any schools?Part of my research involves finding experts on the Internet.  I would really appreciate you answering a few questions for me.  I will take the information you provide me, compare it with what others have said and with other research findings, make some conclusions about my question, and then create a Web site.  
You need to be aware that I may be using any information you provide me on my Web site, but that I will keep your name confidential.  My Web site should be published by the middle of June and will be available on our school Web site (www.courtenaymiddleschool.com).
Here are my questions:
Why isn't there skateboarding at any schools
Do you have any suggestions about this problem?
Why is this even a problem, how did this come to be a problem  (suggestions on that topic)

My email address is [email protected] thank you so much for taking the time to help me with my research.

Hey Ryan! sorry this took so long to reply, my compter screwed up!

skating isnt alowed at school for the simple reasons of liability and propetry damage. if someone was skating in the halls, they could fall and break theyre arm and theyre paretns could sue the school. they also would try to grind everything and chip everything up! or accidently hit a teacher with theyre boards! lol.
good luck man!
