Thanks for the comments, all. I hope to go back to this location at some point to take some more careful and considered shots. There was certainly no shortage of interesting subject matter in the time I was there.
Regarding the PP, goddo, I certainly agree that it could be much bolder. Like photography, I'm new to post processing and am learning as I go. All of the images were edited as jpegs in GIMP. Learning RAW workflow and purchasing a program like Lightroom is certainly something I hope to do soon.
Thanks again. Here's one more....
