What is the theme in Cache Lake Country: Life in the North Woods by John J. Rowlands?

Contentment is the main theme. The first chapter of Cache Lake Country is called "Portage to Contentment", and so from the beginning, the reader will be able to tell that Jim Rowlands finds in Cache Lake Country his spiritual home. It reminds him of the mountains and forests of his youth. When he came upon Cache Lake, it struck him at the ideal lake, a place that no other place could better represent his sense of beauty and peace in the world.
