I'm just trying to remember. I think they reach at least four of the five Great Lakes. I can't remember if there's one to Lake Huron as well, but they're pretty much spread from Minnesota, through Wisconsin, Illinois—with the major one being the Chicago waterway system—and then Indiana, Michigan, Ohio, and I'm pretty sure Pennsylvania and New York. So through all of those states there is the potential of their getting in at least four of the Great Lakes. I'm not sure if there's a vector to Lake Huron as well. But, yes, it's quite spread out on the U.S. side.
