interesting... so they have to dump heat to get lower then reheat to go back up, but how do they steer to follow the hare or like you said "closest" could be relative depending on the wind?It is a game they play, fox and hound or some such. A hare balloon takes off, a few minutes later the hounds take off. The hare occasionally drops a marker, the hounds follow and try to mimic their flight path. The hounds drop markers and get points for getting the closest to the hare’s.
