They use Rt. 30 as one of the roads to transport the blades on. There's a truckstop less than 2 miles as the crow flies from the house, and last Thursday a BMW thought it could drive under the blade as the truck was pulling out of the truckstop. Unfortunately, the blade won.
What I heard was that the spotter was saying "no, no" instead of "stop" and the truck driver thought he was saying "go, go".
