One more thing: a hunting license.
Normally it wouldn't be a big deal, just pay $20 or so for a chit down at the local gear shop, but in a lot of states (all?) now you need to show proof of a hunter safety course. Which also isn't that big a deal either if you can find a course at a time and place you can take it, in time before the first hunt. Now sometimes finding a course at a time and place where you can make it, all in time before bird season begins, now that can be a hassle. The good news is that you probably have plenty of time to get through the course (it's still early August after all), they're free-to-cheap, and most state's fish & wildlife web sites have listings or at least contact info for where to sign up.
Yes, it's one more hoop to jump through, but in the bureaucratic pain-o-meter it falls somewhere between paying a parking ticket and getting your Tech ham license. It really isn't bad at all.
Don't put this one off, it'll sneak up on you and cause you to miss opening day.
