Used to maintain several commercial buildings in a large city (Night Shift). I threw several discs from the roof of a 424' building. My best throw was a Cyclone. It travelled about 1300 feet, then dropped straight down onto another building that I maintained. Drove my car to the other building, went up to the roof, and retieved my cyclone.
For Urban driving, I would recommend distance drivers without your name, and you are willing to loose.
