Impalas are amazing creatures. I found this one at the Tennessee Safari Park, but I have had close encounters with these guys in their natural habitat. When I was on safari in Zimbabwe in 2006 I was riding in the back of a Toyota Tacoma when a herd of impala crossed the rough dirt road at the same time we came by. One of the nimble creatures actually jumped over the hood of the truck in full stride and cleared it easily. It was a very cool thing to see so up close… albeit a bit terrifying in the moment.
