I remember when I was a kid I would bike to a park around a half mile away by myself, definitely before I was 13, and I admit it feels weird to suggest a kid can go to the park down just a single block alone today.

The funny thing is it'd be safer: Kids have cell phones now by like 7 or 8 in a lot of cases and can call for help! Back when I was that age if I got injured or something I might've had to knock on strangers' doors!
