A Last Goodbye #1

In the year 2096, a man and his dog journey through the barren, apocalyptic wasteland that was formerly the United States. On a quest to return home one final time before the earth becomes uninhabitable, this wanderer stumbles across a tribe of mutant cannibals seeking to devour one of the few surviving human communities. Will he trek on and leave the people to their fate, or will he seek redemption for the mistakes of his past?
