The same operator was working today when I went by, he said that you told him someone would be along, but honestly expected someone sooner based on your talk. I told him that normally it would have been followed up much sooner. He seemed to think it was pretty cool but thought that anyone out riding in January was crazy.
Not the best picture, but the stacks are in the background.
And the new tag:
Kind of hard to tell what it is, but it is in Montgomery county. I believe it to be the only iron furnace in the county, and some research indicates that it is, at least, the first furnace recorded from Montgomery county.
Good luck, a little bit of digging should reveal it. If more information is needed, I'll be glad to reveal more (this is my first tag).
