Our fathers had to deal with bicycles.
Then someone invented skateboards and Hula Hoops.
Every generation has had their fads, and the City Fathers had to cope with these new-fangled things.
Now we have Skate Parks, with all their perils and dangers.
(We have a lot of Skate Parks, out here on the Left Coast!)
So we have to make choices;
We can ban them,
We can make every child and their parents sign disclaimers,
We can, (i don't know a third choice)
But the families will move where there is the most/best family facilities!
If you're worried about the lawsuits;
I have it on good authority that the Supreme Court is going to render a decision that say that everyone is responsible for their own actions and the consequences thereof.
It's going to happen! I know it's going to happen!
