Sorry, I was a little rushed before (multitasking). Please let me add a few thoughts.
You may be able to borrow a rifle/shotgun for the season. Many of us gun owners have more than one, and if you are a reputable, responsible, known friend of the person they may extend a loan.
I am serious about the Hunter’s Education. Do it. It may in fact be required in your state to display a course certificate in order to purchase a license. I am a Hunter’s Education instructor, I tend to preach a lot but am also absolutely convinced in what I preach.
A shotgun with slugs can be quite practical for deer, if your expected shooting distance is fairly close range. More than 20 yards or so, go for a rifle. There are a number of common calibers, I had suggested the 30-06 but there are a dozen other ones that are reliable deer class calibers.
Whatever you get, practice with it before hunting season. This is necessary both to familiarize yourself with the weapon and to verify that the sights are accurate.
Hopefully you will get tips from others on the board, there are quite a few people knowledgeable about guns and hunting (review some of the gun control threads).
I Wisconsin, deer hunting is a part of the culture. 700,000 go to the woods each fall for gun hunting alone. The climate and specifics are going to be different from what you will be experiencing, of course, but the basics are the same.
For what it’s worth, I and the devils vacationed at Mammoth Cave National park this summer. Saw deer wandering through the park each day, in broad daylight.
Good luck. Be a safe hunter. Be an ethical hunter. Enjoy the experience.
