In this article from Outdoor Magazine, Carl Zimmer walks into the woods to find out why these tiny beasts are skyrocketing in number – and outsmarting scientists with every bite. The author visits Lyme, Connecticut, the town where Lyme disease was first discovered and writes many interesting things about ticks.
