This from Steve Redick:

I am currently well underway in my latest book offering:

Chicago Fire Rigs at Work Volume 3. I’m about 25 percent done and am quite pleased with the product so far. This edition will feature more photos, and more fire scenes with a lesser emphasis on just rig shots. Enclosed is a mockup of what I think the cover will be … all of course subject to change … This will be available in electronic format as well as soft and hardcover. stay tuned …
