Well, I did it! The one of the roller mill is in my gallery here too. I sent it and one of the Knight Lake dam to the Argus Day folks, we'll see how long it takes to show up.
The weather was not exactly picture postcard lighting -- 95ºF, humid, hazy sun to partly cloudy, but hey, it's Argust!
I'm flabbergasted, I got 25 shots on a 24 exposure roll, all usable, no blank frames and no double exposures -- didn't even smack my fingertips with the cocking lever or stick my finger in front of the lens. Those old skills from the 1960s must be slowly sneaking back.
