That is a crazy machine he made to travel through the woods. It didn't have a steering wheel. It worked like a bull dozer by stopping one set of wheels and pivoting on the other. It was like a tank and could go anywhere, especially with chains on the tires . He used to plow snow with it also.
Pretty wild contraption, it looks like they had fun on it.
So now we all know where you got your outside-the-box thinking. What does he think about your haunting?
