I remember in my younger years deciding to climb "Breakneck Ridge", which lies on the Hudson south of Newburgh, ALONE. I almost, well, broke my neck, and this was before cell phones became common among the youth. After going of the trail and sliding down a steep slope among thorns and poison ivy, I managed to make it down around 8:30 in the evening.
Remember scouts:
1. Always have a map.
2. Always have a compass.
3. Always have a flashlight.
4. Always have a buddy.
5. Never leave the trail.
and probably a loud whistle you could hang around your neck would be a good idea also
