I recently tried several bags of a local produce, stone ground Rye Flour, from a place called Trade Mill, which is in Trade Tennessee near Wautaga Lake. 
Food City, a local chain of grocery stores, has this product and it's both more reasonably priced than a competitor's rye, and has a more interesting texture as far as I can tell and taste. It might be that it's more freshly ground.

They have an interesting website with videos.
