Small world! I may have a few of Allegro shoes before they took it down (I think that one is the one that was torn down in the 80s). Snyder bikes and the Gilbert knitting mill were also in the same area. I'm not too sure which are still standing and which are gone.
The Daniel Green shoe factory in Dolgeville (next town over) is still there though the factory closed - it's now an antiques mall.
The Mohawk Valley area has lots of broken down old buildings to photograph - which I only realized after I moved. My parents and G-mom are still there, but I don't get back as often as I should.
