David and Johnny, aged twelve and ten, go from Kansas City to Colorado for their summer vacation. They are taken off on a grand pack trip by an old-timer called Ike. They experience all the joys of such an expedition including meals of fresh-trout and beans. Excitement runs high when they cross the path of some saboteurs who plan to dynamite the great dam. This is a good one to remember when you have calls for books on western camping.
