That moose is not even trying. During a 1999 trip to Yellowstone, one of them got tired of the crowd of onlookers cramping his style in a meadow. He was about 100 yards off the road. I was about 20 yards off the road. I noticed he was getting perturbed (he'd stopped eating and had fixed a beady eye on us), and looked for an exit route just in case. When I looked back I saw him take off towards us. I pretty much teleported myself onto the top of a piece of road construction equipment that was parked on the shoulder. In the time it took me to cover 20 yards, he covered about 80 - and for a human I'm not slow. All the other scattering people probably slowed him some too as he tried to figure out who to toss. In the end, he seemed satisfied with the results and walked off. I waited till he was out of sight before getting down from the grader/loader thing.
