At Cedar Point in order to be allowed to operate a ride, one must be 18.
Here in WV and in PA where I used to live, one must be 18 to operate the cardboard compactor at the store where I am employed.
In most states, the age of sexual consent is 18 years old.
One must be 18 to vote in an election.
One must be 18 to buy cigarettes.
One must be 18 to be allowed into an R rated movie without a parent.
So are all of those age restrictions pointless?
Yes, a lot of kids are very mature for their age. I have nothing against teenagers. It is easier for me to trust a legal adult than it is to trust a "youth" when my life is concerned. Rides are very large machines with moving parts. I am fine with kids under 18 working at the games booth or the Dippn' Dots stand, for example.
I can understand the poor attitude some of you have about the lawmakers in this story. Motives are a big interest of mine, and you all seem to have a good point there.
