Look at the "safari planner" for questions and issues.
Do you each get these species or do you have to share? You adding more?
It will be helpful if you can give us more specific questions, e.g. what rifle to take, what clothes to wear etc.
Welcome to a great forum. I'm a new guy, just made my first trip to SA last spring. Here are couple of things that pop into my mind (some have already been said):
Wear your good, worn in boots on the plane and change into slippers on board. That way if your luggage gets lost you still have the most important part of your wardrobe that can't be replaced en route.
Start working out now, you are going to walk, crawl and slither a lot if your hunt and outfitter are any good.
The animals in your package are not guaranteed, they are just included if you get the shots and kill them. Start shooting now, and do it as much as you can. Most PH's try to get you in to less than 200 yards for your shot.
If your PH says "That is a really GOOD (fill in the blank), you need to take it", do it if you can afford the trophy fee and even if you can't.
If you plan to use the outfitter's rifles take an ammo pouch with you to put on your belt. It would have saved me from an embarrassing experience I had taken one.
Keep checking in here and asking any and all questions your have. Folks here are really helpful.
If there's room for the hunt this year you can do it, just get going on the passport NOW! I wear my first mornings clothes (for a cool morning) and boots on board. I carry moccasins in my on board backpack for the flight. I keep all my prescriptions, camera, paperback books, glasses etc in that backpack. If I have nothing else I can hunt 10 days that way. Don't sweat the small stuff, you've got enough time. Just keep asking questions here.
Welcome .300wby !
Some great tips posted already above.
Consider adding 3 or more days if you can swing it.
It may take you a day or two to get over the jet lag and adjust to the time change.
Ducks Unlimited you say? F.Y.I there are some great wing shooting opportunities available there.
Preparing for your hunt and the anticipation is a good portion of the fun.
You should have a great time even if you didnt discover a new species to shoot at. Lots of info here and lots of knowledgeable hunters.
Know Mark Hudson very well we hunted together at John X safari's in 99' shortly afterwards he went solo, Talk to him he runs a good outfit and places allot of focus on personalized attention. He will be more than happy to accomodate and answer any and all that you might have.
Have a great time.
My best always.
Welcome to the forum. Enjoy it! There is a great deal of information.
