LOVELAND, Colo. - Against the majestic backdrop of the Rocky Mountains, in the far eastern corner of Colorado where the land begins to flatten into a vast golden prairie, two teenagers trudge along the weed-bitten edge of an isolated highway. Blistered and sunburned, they endure wind, rain and searing heat. But still, they slog forward in what has become a quixotic journey across the country in an effort to end the Iraq war.

Ashley Casale, 19, and Michael Israel, 18, are walking 3,000 miles from San Francisco to Washington in a trek they once had hoped would rally the nation and lead thousands to join them in their epic March for Peace. But, nearly halfway through their trip, the teens remain alone, wandering the vast landscape of America, where few have paid them any attention.
