Many years ago the Forrest Service tallied up the totals for the deer population outside of a national park in CA. The determination was that several thousand deer needed to be “culled” or else the deer would be overpopulated and starve to death in the winter snow. So the “culling” of the deer commenced, and the Forrest Service was surprised how hard it was to find all the deer to “cull”. They finally achieved their goal (using helicopters and airplanes) and disaster was averted. The only problem was that the person who was responsible for doing the math somehow forgot to carry a decimal point (or was just lousy at math) and it was later determined that almost the entire deer population was wiped out in the area as a result. Oops! Locals say it took 20 years for the deer herds to reappear.
