Pronghorn Food on Flickr.

This is the fastest land mammal in the Western Hemisphere and second only to the cheetah. It can reach speeds of up to 62mph, but can sustain those speeds for longer than a cheetah. This one had no interest in showcasing his speed for me, but just happily grazed while giving me the occasional glance.
