Depends if I'm on public or private land. Public land, I'll kill just about the first deer I see. The private land I hunt is managed, so we let the basket racks go. We shoot mainly does or bucks over 5 years old. I personally can't tell how old a deer is by looking at it from a tree. I just always tell the others;
"I had to let several pass because they were too young. So I took this doe instead."
I took a doe the first weekend. Now I'm concentrating on the soon to be migrating flocks of waterfowl.
I am going to try and get a fox kill with a bow on film this year though. I shot 3 last year and one of them was 15 yards away. Bad thing about capturing it on film is that it puts more people out there and those little carniverous buggers have spome excellent noses.
