From DJ flap - The shield of a firefighter's helmet gets blackened from experience, from meeting the challenges and confronting the dangers of the job day after day, night after night, from taking walking tours of hell with the devil as your guide. The author worked as a firefighter in one of New England's oldest, most densely populated cities during perhaps the most challenging period in the history of the American fire service, the 60s, 70s and early 80s.
