If you live in the eastern US (I guess anywhere but within major metro centers) it becomes pretty obvious pretty quickly, but likely more for long time residents than others. My brother in law is a veterinarian and he got a "deer population control" hunting license last year that allowed him to take up to 40 deer. Our collective freezers are chock full of venison. Luckily, someone had a brilliant idea to create a meat donation charity (Hunters for the Hungry), which has distributed millions of pounds of venison to the needy over the past couple decades. Here's an information clearinghouse for anyone interested: http://huntingprograms.nra.org/hunters-for-the-hungry-inform...)
