One of the advantages of the guide book maps is that they've been around
for years and had many revisions. The authors have gotten years worth of
feedback to correct many of their mistakes. My experience was that they
were rarely wrong. Since then, folks with GPS devices have found mistakes
but I suspect that's more due to inaccuracies in the underlying USGS maps.
