There are just too many options. 50 , even 30 years ago, you didn't have the "internet". You didn't have a tv in every room. You didn't have cell phones for everyone in your household. Cable tv had far less than the 99 available options the box was capable of. Sports were not as available then as they are now.
Why is it that we don't think it's acceptable for a young child to be out on his/her own? Al mentioned being a kid and going to the river alone. I believe it's the media's fault to start. How many more children are taken nowadays vs 50 years ago? 1 is too many, but how badly are we hurting the children by restricting them? When is it ok for them to spread their wings? At that time, what are they prepared for? How did they prepare? Because of 'age' ?
Sorry for the rant. I Grew up in South St Louis city, 4th of 5 kids. We roamed that city safely for many years without being killed, abducted, shot, etc. It just bothers me when kids are not allowed to be kids.
