Dust of Destruction

A young rancher's alfalfa crops seem to be dying and they can't figure out what is causing his crop to dry up. Sky volunteers to fly samples to a lab in Tucson, with the promise to have their report back later that afternoon. Turns out that someone has been putting weed killing poison in the crop duster. If something drastic isn't done in the next two or three days, the crop will be lost and nothing will be able to grow there ever again. Sky calls Penny and tell her that the crop needs to be cut right away, so she needs to round up as many people as she can. Luckily there is a ranchers' meeting at the local Farm Bureau, so she hurries over in hopes of enlisting others to help with the mowing.
