I were thinking of my experience in Russia where engineers, mathematicians, and physicists absolutely loved going out on various nature trips (Didn't really think of Sheldon and US tv shows). Of course, not everyone did, but we're dropping a huge number of people, and those who know can teach those who don't. Healthy person can go for 2 months without food.

Let's say that they spawn on 1kmx1km zone in a grid with 10m spacing, in the temperate climate in the late spring, clothed in earliest stone age clothing (for same reason why we don't spawn dolphins into a desert, we don't spawn people into the Arctic).
