Review: "The Howling Hills" by Charley Phipps

This is not the greatest module in the world.
This is a tribute.

Charley Phipps' The Howling Hills is a free adventure for AD&D First Edition and its clones.  The material could be used with other TSR or OSR rules without much conversion.  The scenario aims to challenge high level adventurers - no mean feat in any game - and also has to deal with the problem of very skilled players.
