otherwise - not so hard.
find a large stretch of primitive land. relatively flat.
lay out a triangle on a sketch map .... with bearings for each leg.
go hike the triangle, and see how close you get to your starting point when you get back.
this is a great little exercise, and not nearly as easy as it sounds.
HINT: park your truck so its clearly visible on a backroad. make yourt starting point somewhere
on that road, where you can see the truck from the start. otherwise when you get back, you
can do a lot of walking to find your vehicle.
