I just realised after listening to war of the worlds original broadcast by Orson Welles , ground zero was Grovers mill , there is even a photograph of a huge barn with " Grovers mill " emblazoned across it .
So the quest to clear out " Gryver’s mill" must be a nod to that classic radio show 
Hadn’t considered this, but good pickup. 
The thing I love most about Gryver’s Mill is that I was the first to suggest such an area, back when Crate was taking suggestions on new environments.
Not to say GD would be absent Gryver’s had I not suggested this of course, but I will forever love how the mill we got in-game is so visually similar to the one from my post’s source image - dam bridge and all! 
Really nice find

@ Younghappy, i love moments like that. When you suggest something and then it happens. You have no idea if it was in fact you or not but, you still feel like you inspired the idea 
Will add it now thanks Arnge .
Younghappy thats brill
