Walking the Big Wild: From Yellowstone to Yukon on the Grizzly Bear's Trail Book

The author walked from Yellowstone to the Yukon in order to publicize and promote the Y2Y wildlife corridor initiative and also to evaluate whether there was enough wilderness to support certain wide-roaming keystone species such as the grizzly and wolverine. This account of his journey is an honest adventure story where he's not afraid to present himself as at times a person with poor judgment or other failings. I was glad to read about it but even gladder not to have experienced the many discomforts and stresses of the trip itself - it certainly killed any ambition I might have had along those lines!
