I have a wood fireplace downstairs and although it won't heat the whole house it can heat the room it is in very well. I also have a kero space heater and plan on storing about 50 L of fuel. I have several other stoves and lanterns as well with fuel to last about a month or so. If that were to be used up In an emergency we could just pull the mattress from our bed and place it on the floor near the fire place and we could be very comfortable. I have no well but the Ottawa river is close enough. I may invest in a more comprehensive water purification system maybe, depending on if I feel I really need one. If not I could just boil the water over the fire if all other means(stoves) and the like were out of fuel. There is plenty of dry fallen wood close a hand. More than I could burn In a year for certain. Time permitting I will start cutting some up and stacking it. Emergencies aside, nothing is better than curling up next to a warm fire with a glass of scotch.
I have a good chainsaw, and plenty of cutting tools like axes, machetes and a sword collection to boot. Not like I would ever need to resort to that but hey, weirder things have happened.
I think I will let the deer on my land live, and hunt somewhere else this season(except for the giant buck, his ass is mine

there are a bunch of apple trees out back where they come and feed regularly. If I don't murder them and I keep feeding them they will always come back. I don't have to go far in Ontario to find deer elsewhere so if I keep the ones on my land happy In an emergency I potentially have hundreds of pounds of fresh meat ready to go.
I may be on to something here.
