I realize that the RM Elk is closer related to the Eastern elk than red stag, but the eastern elk was somewhat amaller than the RM elk.
The Elk in Pa were introduced, I believe in the late 1800s from rocky mt. stock.
The origional eastern elk is believed to be extinct.

With the lack of large remote areas in many states, it seems that the smaller Red Deer would be more practical than the larger elk.
I have watched several hunting programs of red deer hunting in New Zealand where they are truely wild and free ranging and they are magnificent animals.

Again I was just curious to know if they were ever introduced into the wild anywhere in the US, I realize that they are commonly farm raised,surely over the years some have escaped or were released into the wild in places like Texas Etc.
that established themselves as free ranging animals.
