Back in the '60s when I was a teenager, I loved to read stories by Robert Ruark. He wrote for Field and Stream and wrote many books about hunting and fishing. He always made you feel the mystery, excitement and beauty of the outdoors, and I could well imagine myself out in the woods with the "Old Man" learning the ways of the wild. Here's a link to a short bio and an excerpt from his book The Old Man and the Boy. http://www.ncwriters.org/services/lhof/inductees/rruark.htm .
But his account of his Safari to Africa Horn of the Hunter http://www.amazon.com/Horn-Hunter-Story-African-Safari/dp/1571572635/ref=pd_bbs_sr_1/002-3619153-9514442?ie=UTF8&s=books&qid=1179517117&sr=1-1 has always stood out in my mind. Ruark had actually hired as his guide the same guide Ernest Hemmingway had used. Hemmingway, Ruark, and an African Safari were pretty heady reading for a teenager / US Marine in 1964.
