Parts of WV would be pretty tough. A couple of weeks ago we got about 6" of snow here in Richmond, VA. Mom and Dad got 31" there in Greenbrier County. WestVaCo's clear cutting policies have about wiped out the squirrels around home. Some years dad manages to kill 5 or 6 (that's right, all fall). No den trees and few trees big enough to have a good mast crop leave them little reason to stay in the area.
The deer population has picked up but it remains to be seen what the growing coyote poplutaion will do to them. Not many rabbits either. Every 3 or 4 years they'll get a rabbit the dogs run across while bird/squirrel hunting. There used to be lots of grouse and turkeys but their population has drastically dropped off the last 8 or 10 years, maybe due to the coyotes, maybe not.
Fishing? If you like little fish. I mean you can catch a stringer full of little fish and little fish is still fish, it just takes more of them. Are there big fish up there? Yeah, but the policies of the Army Corps of Engineers use (letting most of the water out of the lakes in the fall/winter) don't allow for stable habitat in what is shallow water during the warmer months. They stock fish all over the place as the "native" populations just don't provide enough new fish every year to maintain levels. That and some of the locals don't mind taking home 70 or 80 stocked trout a day if they can get by the game wardens.
You know the indians didn't even stay in some parts of the state during the winter months. They moved in in the spring, hunted and fished and gathered and camped and then went home in the fall.
There's lots of wild strawberries (man are they ever good!!), black berries, rasberries, a few huckleberries if you know where to go, lots of apple trees (but due to the weather they sometimes go two or three years without apples due to late frosts in the spring), no such thing as peach or pear trees in that area and wild mushrooms if you know what's safe to gather and cook.
You want to know how hard it is to make a living farming in that area? Most of the smaller farms were abandoned when jobs became available in the mines in the '20's and '30's. My dad remembers a few of them having houses/families living on them when he was growing up in the '30's and '40's but since I was a kid they are just names (the Wade place, the Beckner place, the Burdette place, etc,. etc.) and there's not even a piece of a building standing on any of them that I ever remember seeing.
There are much nicer parts of WV. Mostly over to the west where its more like southern Ohio. Rolling hills and warmer temps in the winter.
Having said all the above, one reason I like it up there was I could go hunting all day and never see another person, or go shooting and never have someone come by and bother me, or go fishing in a creek or pond and probably not see anyone. I really miss it. I'm not anti-social, I just act like it.
