Thank you for the compliment. I appreciate it a lot.
I've already written a few trade journal articles.
I'm currently working on a two-part structural collapse article, and I was a recent contributor to the new Jones & Bartlett Swiftwater and Flood Rescue FOG (field operations guide). Jez Hunter was the primary author. Jez and I are currently writing a rescue text that should be out next year, and I also wrote the water rescue chapter for the soon-to-be-published Technical Rescue book that J&B is also publishing.
I'm considering shopping a monthly editorial column to one of the fire-rescue trade journals, something along the lines of what you suggested.
