Living out in the country, I have a 500 gallon propane tank for the furnace, stove and water heater. I also have 3 25lb tanks for the grill. So I'm good for a while.
But if I run low, I have a couple of fire pits and plenty of oak, apple, cherry wood that I can use to cook over. Also the occasional deer runs through the yard if the meat supplies run low. Not to mention the rabbit, turkey and other eatable critters that roam around here.
