i get a kick out of the thought people put into the stripes their mowers leave. buying extra parts for their mowers and whatnot. i have tested the theory that a lawn with perfect stripes pleases the customer on quite nice properties, and frankly they dont really care. i have done figure 8's and circles on lawns and i did that whole mind mezmorizing box. As hard as i used to try to make straight lines in the lawns, curved lines is what i usually end up with cuz the speed is more important to me, its not that important. anyways thats just what i think.
