Good luck with that wish... I had one I THOUGHT was "alone" through the winter and early spring of 2015... by summer it was like the old Star Trek "Tribbles" episode with dozens of them running around. Darn things rooted swimming pool sized areas in each of my fields and when it got really dry, dug out an area every bit as wide as a 2 lane highway around my pond. Helped me be a bit more understanding about the folks who use tannernite against them.
