Tough Shot 6: Out on the Prairie When the Wind Is Blowing and You're from the East and Haven't Seen a Deer in the Open Before
Less-than-charitable Western outfitters call it "Pennsylvania hunter syndrome-¿; a nimrod takes an easy shot and turns it into a tough one by:

(a) Overestimating the range. Deer look much farther away when they're in the open. Use a rangefinder.

(b) Overestimating the effects of wind on the bullet. Unless you're 300 yards away or more, and/or you're shooting in a cyclone, the effects are negligible. Hold on the vitals.
