Personally I think having coastal access would make feral living more possible. For example we have urchin, mollusks, fin-fish, ground-fish, seaweed, etc all year round in the ocean.... The area around Bella Coola and up into the Chilcotin has both interior mountain terrain, good for moose and bear hunting, as well as coastal access... Skeena drainage also good.
I have some friends in Southern Yukon, not far from Carcross, homesteading there. Beautiful place- they grow food (potatoes, carrots, greens, etc) and have a greenhouse and hunt and fish.
