Hello Jim and a big welcome from Albany, New York. I join only two weeks ago and for the same reasons as you, but I don't have Lyle's book yet (it has been on order for 2 weeks) but I did hit on his web site Micronavigation. I'm not a hiker or a person who does or will spend time in the outdoors, but I love reading about it and dreaming. Jim, these guys literally know it all regarding land navigation.
