Fantastic, we had an orienteering exercise at school when I was about 15. There were 5 of us with backpacks, tents and food and water to last 2 days. At about 6am, we were taken out in a van with the windows covered up and dropped somewhere in thetford forest and told that we were expected back sometime that evening.
It was good fun and at no point in the day/night were we worried by cows, there was the occasional public house along the way, but that was all to the good

Honestly I sometimes wonder about the sturdiness of today's youth about town; it's the 'about town' bit where everything seems to go wrong.
We had no phones, just maps and the assurance that if we hadn't arrived by 10pm then people would start to look for us lol. We did get quite wet and a bit cold in the morning when it chucked it down, but that dried off with the rest of the days walking.
Happy days...
