Yep. I've got dozens of potatoes growing maintenance free in in a few square yards. Next year I aim to do half the yard, even if I don't harvest them. They are big yield for little work. When starving without choice I'd rather eat potatoes than a Rosemary bush. I live half a block from the freshwater of the Detroit River (pros/cons). My neighbour feeds squirrels peanuts, but there are only so many of them around to trap if it comes to that.
