I'd be willing to trade a chestnut problem for your walnut problem. With chestnuts, you get these prickly little needles all over the pods that come back to haunt you the next time you kneel down on your knee. Talk about painful! The nuts do make for nice fireworks when you pile them and burn them with the hulls. I have both chestnut and walnut trees, but I'll take walnuts over chestnuts any day.
