I grew up in a safe neighborhood with a ton of twisting bike trails that weave through the various villages, but, are "behind" them in natural landscape so you always felt like you were in another world. As a kid, these trails were the source of so much happiness and joy. I could hop on my bike, and go explore. Miles and miles of trails. As I grew up, I would venture further and further on the trails. There are a couple points where the trails exit the safe neighborhood area, and connect up to the more general biking trails ... those were always such fascinating boundaries for me as a child. I'll never forget the thrill of crossing over into that forbidden land on my little 1 speed bike. I was probably 8. I don't plan to have kids but if I did, I would really want to ensure that they had a source of mystery and adventure which was their own. A sense of independence and freedom to explore.
