I was driving down the road in the Dunwoody suburbs and saw a young buck upside down impaled by a metal fence post through his hind leg. The fence was about 6 feet tall. I knocked on the homeowner's door and he came out and we pushed it off the fence. I was holding up his front half while the homeowner pushed his leg off the fence and threw it over. I was cradling the deer with blood spewing out and the deer made a roar/scream that I have never heard a deer make. It shocked me so I dropped the deer and ran. The homeowner's 3 year old kid was crying hysterically.
