i kid you not. this is a true storey. Once quite recently, near canberra, i was driving down a rough dirt road, flanked by 1.5m high rural fences on either side of the road. The width of the road reserve was probably about 8m. There was a mob of kangaros, with two stuck on one side. one was a very big buck, the other looked like a female, but cant be sure. Effortlessly, as i drove down this road, the buck lept over the two fences and the road in one jump. I clocked him at over 40kmh and he got airborne that was well above the height of the truck. They can be pretty energetic....There have been numerous fatalities on australian roads from roos. one case that i know of, the roo came through the screen and decapitated the occupants as it travelled from the front of the vehicle to the back. That animal is understood to have survived the encounter.
