As an 11-year-old I used to love sleeping out in the 'wild'.
I'd go to bed as normal, then when my folks went to bed, I'd sneak out and meet up with a couple of mates.
We'd make a fire and have a fry-up first, of course

, then creep into our sleeping bags and tell stories to each other. One of us had an alarm clock and we'd make sure we got home before our families discovered that we were gone. I shared a room with my brother and he was sworn to secrecy. Otherwise he'd get a duffing.

We didn't go out if it was wet or too cold.

I think kids should be encouraged/forced

to sleep in the open from time to time; 'tis character building.
