The worst thing that has happened to discourage a "natural childhood" since my misspent youth is the amount of legislation about the environment and children. Most of the things my mates and I got up to would be illegal nowadays, and there are so many intefering busybodies who call themselves "Wardens" or "Rangers" or some other pompous title, who's sole interest seems to prevent anybody (especially kids) enjoying the countryside.
The area where we used to play, climb trees, build dens and camp out is now a country park, and all of the above activities are now banned (including playing outside of the officially designated "play areas"). The official excuses for this attitude are that these activities are damaging to the environment or are dangerous.
I have two sons, one 11 and the other 6, who both like being outdoors, but I can't let them loose like I was, not because of traffic or "stranger danger", but because there is nowhere that they can be let loose without one or more of the above-mentioned pompous idiots taking an interest, and then involving more of their kind in the way I choose to bring up my kids. I even had a (friendly) warning from a member of staff at their school that if I took them for a month-long camping trip during the school holidays that the local Social Services would be on my back on the grounds that I was failing to provide suitable accomodation i.e. no running water, bath/shower, etc.
Annoyingly, considering the report was produced by the National Trust, some of their staff are the worst offenders when it comes to the "look but don't touch" attitude to the countryside.
RANT OVER!
