I was driving to Jackson Hole in Grand Teton National Park from Yellowstone National park , Wyoming when I saw the two Antelopes very near to the road .I stopped right away and jumped out of the car to capture some pictures of the Duo .It was kind of dark at that time and I had to get the shots before it becomes darker . The only issue with Yellowstone National park / Grand Teton national park is , whenever a tourist sees a car parked near the road or sees somebody with a camera (most of the time with a Proffessional camera kit ) , they tend to stop suddenly and scare the animals . Most of the time its the closing of the door which frighten the animals . And here also the same happened . And I had to walk quietly for some time to be near to the animal again and get the right shots. Anyways I guess it was worth the patience .Enjoy .
