When I was a kid I rode my bike all around town, to my friend houses to the park ect... I was only home to eat dinner and sleep.
My daughter just turned 7, the age I was doing all of that above and there is no way I would let her jump on her bike and do what she wants! I did grow up in the middle of nowhere but still I think wtf were my parents thinking!
My daughter would LOVE to be able to do what I did as a kid, but it's just not going to happen. I let her run a muck outside but its always supervised.
