Also, parenting and childing were different back then (the 70's). For example, I remember when I was 16 I secretly hitchhiked solo from Detroit to Washington DC and then Chicago and back to Detroit. I explained my absence to my parents by telling them that I was riding with some friends to DC, that is, it was totally okay for three 16 year old boys to take off to another city back then. Now, I think a lot more parents wouldn't allow their kids to do that.
