If it's not too much to ask, what state do you plan on hunting in? Hunting regulations vary from state to state. Some require tags and some don't.
Also I would suggest that you maintain ONE thread on the subject instead of starting a new one every time a new question pops into your head.
Being able to understand a book of hunting regulations is a required skill if you are going to go hunting and stay out of trouble. Do a Google search on
(your state) hunting regulations
and you should be able to find what you need.
