I still have the bike I rode all those years. It is a swing bike (not Schwinn, Swing) and it has a headset under the seat, and the back wheel turns like the front wheel. Mine was originally orange. I painted it several times, but the last time, I painted it black, and put on five spoke black mag wheels. Here is a picture of a swing bike:

So picture me on the back of this thing now, 100 pounds heavier than when I rode it all the time. But, I still got it! It is fun to ride, but I decided that the time was right to buy a new bike. I ordered it today. Here is a picture of the new one:

Now, while I am ordering mine, I approach Carl, and ask him if he would like a cool new bike, since his old one has seen its better days. He was like, "Eh." The girls have cool bikes, and Lara also indicated she would rather have surgery than ride bikes. This is a fundamental way in which we are different.
The title of the post, however, relates to how as parents, we just can't let Carl, Maggie, or Katie just go riding, like I used to when I was a kid. I'm not one of those who look back and say, "In my day, we could...(insert your own hyperbole here)." BUT, there is no way in hell I would let Carl ride over to his buddy's house across town by himself, let alone take a five mile ride in the country on his own twice a day.
If the times haven't changed, if bike riding hasn't changed, then I can only ask "What the hell were my parents thinking 30 years ago?!?!?"
Of course, the times have changed, and riding bikes has changed, too. But, I'm looking forward to the new cruiser.
