I like to take one or two deer in overpopulated areas early in the year (September) I don't eat more than 2 and give some away to my club and others.
It reminds me why I'm out there, keeps me fresh on shooting live animals and tracking. I then can take most of October off keep spots fresh, and know my equipment and shooting is in order for the Rut. Then looking for big bucks the rest of the year isn't such a big deal if I don't take anything.
The real reality is if your hunting only for meat. You can buy beef much cheaper at the store when you figure in time, equipment, license, fees, gas, wear and tear, travel, etc....
I realize we hunt for more reasons than that, but when a guy tells me he's a meat hunter, and only out here to feed his family.....I tell him go buy it at the store, its cheaper.
