Now this is what I call proper use of technology. The floodwater was too swift to get somebody to the trailer, and they couldn’t get them a line because it was too far away. In comes a volunteer who uses his drone for good deeds. Because of the drone, they were able to get them a lead line to a heavier rope, and use the rope to cross the swift waters. Nicely done!
