I think I was to quick to blame the rabbits for eating all of my sweet potatoes. I remembered that in all the many years I've grown them that they have never eaten them before, so why now. And also they dug up the roots and ate them too! I've never known rabbits to do that. Soooooo A few days ago, what do I see but a ground hog! I'm guessing he's the culprit. My appologies to all the bunnies, (Even though they have eaten all my beans.)
