Paramount Paragraphics: Oregon Steelhead (1937)

Zane Grey gives lessons in fishing in Oregon. The first lesson is to survey the selected spot of a high vantage point. It is necessary to shoot some rapids to get to the spot Grey selects. Then one of the two cameramen, Harry Anderson or Gus Bagnard, shoots some underwater footage. Later, Grey finds that none of the fishing flies he has are the proper type, so he makes his own. With those, he lands some good size steelhead trout, which all hands enjoy for supper.
