I'll say this about Land Nav.
It is the first time for a lot of people that everything is on "YOU". A person knows the basics but after that "YOU" have to apply it.
You start to fall behind, miss a point, can you regroup or do you panic and start running through the woods hoping to find something? Do you get rattled, loose gear, drop things, where's your map? Try to make up time, run the roads? Take the short cut where all the blue and brown lines come together?
Yeah, Land Nav can be a life changing experience for some.
I liked it because you were on your own, all night, just a walk in the woods.
