Way, way back in the 70s, when I lived in the Dallas/Fort Worth Metroplex (yeah, that's what it's called ) and was all of 15 years old, my parents would take my two brothers and me to Six Flags Over Texas on Saturdays. They'd srop us off at the main gate at about 1PM and then pick us up at 10PM after the park closed. As I said, I was 15. My brothers were ten and nine.
Let me repeat that: I was 15 and my brothers were 10 and 9. And we didn't go with each other, we three split up at the gate and never ran into each other again the whole time we were there except by accident. My parents weren't the least bit afraid that anything bad would happen to us, that we wouldn't be robbed or molested or anything. The worst that they thought would happen was that we'd spend all our money in the arcades and not eat anything (and food was reasonably priced, like $2.00 for a burger, fries and a soda; my dad gave us three $5 apiece and we could make that last all day).
Anyway, were our parents being foolish or irresponsible by letting my 9-year-old brother vist a theme park alone? Would you do this yourselves? Today, I think a kid should be no less than 15 to go alone, even to DLR. Am I being paranoid? Have times changed or is it me?
