bret: finally tonight, fight or flight. when it comes to a cheetah vs. an impala, the impala always chooses flight. and it was a wild chase all caught on camera. a group of impalas chased by two cheetahs in south africa with park goers watching and taping the whole thing. these are some smart impalas. the fastest animal on land we knee is the cheetah. cheetahs aren t quite as talented as the impala. beautiful shot of impalas being chased by cheetahs unless you are the impala. then it appears that the hunters cheetah separate one from the family. the spectators watching the chase, quinn, the lone doe watched to the right here jumped into that suv. boom! right there. now, the impala is inside the suv. thank god the impala left. the cheetah its also left. amazing. smart impalas. thanks for i inviting us into
