Reading some of these comments, it becomes very apparent why more and more legally mandated requirements are put in place to protect the resource.
For the meat hunters, letting a deer live to at least three years old usually will produce a deer that has substantially more body weight of a one year old.
You'll start shooting big deer, body weight and/or rack size, when you quit shooting small deer.
Start from what is best for the animals as a whole, conserve the resource.
