Sometimes I think the states have handicapped themselves by putting age requirements on hunting. Some states won't let them hunt until they are 12-14 years old. By then, it is probably too late. The younger they get involved, the better.
Parents that hunt will be able to take their own children hunting but what about all those kids being raised by single mothers that don't hunt? No exposure to it before the teen years means they will probably not be interested. The various game departments of the states need to find a way to reach these kids.
