Hi again, David,
The first thing that struck me about this series (photographically) is the heavy overcast sky, that alone adds a lot to the “Ghost Town Story” in my opinion.
Remember, everything I say is always “Just my opinion”, there are no rules, there may be some loose guidelines maybe, but no rules and it’s always subjective.
Ten People can see things ten different ways which brings me to the term “Photojournalism”, that term used to be heavily associated with bad things like war or devastation from a tornado or a hurricane, etc. but artistic images like the ones you have here can be presented in a photojournalistic “Style” where the images tell a story on their own, but some amount of commentary always helps with context.
This still living and breathing ghost town has a great story that deserves some factual and historical context and the commentary you provided here done a great job of describing what things might have been like for the community during its heyday. I can now imagine what it must have looked like to have wagon loads of wool coming into town from the whole of Central Oregon so they could sell their wool or trade it for other goods they might need back on the ranch.
I imagine travelers coming in by coach or horseback needing a rest, a bath, a good meal and a refreshing spirit or two (or three or four 
) Or…maybe just a good sarsaparilla.
Commentary and presentation Well Done IMHO.
Photographically, I really like all of the images as they are, the perspective, framing, consistent tonal range from one image to the next, all well done!
I like the wide open shots at the beginning for a good sense of the environment as well as a glimpse of what coach and horseback travelers might have seen first when the town started coming into view.
The fire truck with the lone tree is great, and the one from the right side of the truck with the buildings in the BG is really good too because the truck is the most prominent thing in that shot.
The two vertical tight shots from 2009 and 2012 are awesome and not just for their perspectives but also for the amount of frost and ice build-up that really does well at showing the relentless and blistering wind coming from the side. BTW, it took me a minute to figure out that the image above the headlight was of the pressure gauges at the water inlet and valves on the front (a little mystery is always good ).
Personally, I like the tight shot of the left window with the mirror to the side, to me, it shows better what the driver might have been faced with as he or she needed to get in the truck to go out and help save a home or business.
The tight shot of the hose reel is awesome as well because it shows the simplistic and practical way it was used as well as an artistic quality with the subtle highlights and shadows. The progressive light to dark under the hose reel frame really shows the depth well.
And the bottom wide shot with the ominous sky has a unique feel of it’s own, it’s like I know that the truck may soon not be visible from either heavy snow or just be totally obscured by the impending storm itself.
This is all great, especially since you didn’t take the shots with any story telling commentary in mind at the time.
Love it and I look forward to the next part of the story!
Did you happen to get a shot of the old horse drawn paddy wagon by any chance? Just curious.
Even though it takes a little over three hours to get there, meaning leaving home at O’dark thirty. It’s still worth it every time. I always come back with one or two keepers.
