Seasonal Disorder: Ranger Tales from Glacier National Park Pat Hagan First edition

Claiming there's too much to explore and discover in Glacier National Park that you can't do it all in one season, Park Ranger Pat Hagan returns every summer, year after year. While some people suffer from Season Affective Disorder (SAD), Hagan says he suffers from "Seasonal Disorder" (SD), a type of depression that results during the remaining seasons-which are: Almost Winter, Winter, Still Winter and Construction. Seasonal Disorder is about spending summer in paradise-for as long as you can make it last.
