Deer hunting. Not pygmy hunting.

Three survivors in the remaining world, seemingly devoid of life... all is not lost, for remnants of society abound, and technologies can be thus relearned... but first, to find food...

This seems to be in California, but anyway, the surrounding land seems too dry to farm (count not taken that farming for three people is somewhat ludicrous) so they look for game to hunt... They see a herd of something in the trees on a terraced hill by the road... initial impression, deer, running... soon turns out to be a race of short men, like dwarfs or pygmies... They are human, screw hunting them... of course, with some communication they may be taught to extend human legacy when the old races die off...
