Thomas Skaggs, Foothills of Mount Level
I just spent the day working with walnut....and wearing a mask. I am allergic to walnut dust. Breathing too much makes me feel like I have the flu. Oddly enough, I can eat walnuts with no problems. The wood has a natural herbicide called juglone. I'm pretty sure that is what makes me sick. None the less, a mask is a must for me!
