Quick and dirty:
- fly through Frankfurt not Londons Heathrow
- arrange your gear so it can be lugged on wheels, while traversing the airports etc Tuffpacs are good
- Melatonin is really good for sleeping on the plane and no hangover
- talk to your PH before you arrive and sort out the airport tipping etc. a good PH will have all of that stuff arranged before you arrive and it should not cost you anything
- slow down... nothing happens fast over there, Africa time is way different than yours and all you will do is agravate yourself by getting in a rush
- your ph will be very impressed if you show up with a well used rifle shooting heavy for caliber bullets
- bring the max allowable ammo and if your PH shoots the same caliber leave what you don't shoot with him
- Malarone is my prefered daily malaria profaxis, do not take on an empty stomach
- something with 99% Deet is required to keep Tse Tse flies away
- Cipro broad spectrum antibiotic, Immodium and Gravol should be in your pack, this is for anything and everything that can make you sick, leave it for the PH when you leave
- bring a tupperware medicine pack, antibiotics, ibupro, bandages, Polysporin, tensors, sutures, tape etc. You may not use it but the camp will sure appreciate you leaving it for them when you leave
- practice shooting off sticks in a standing position and realise that as soon as you get into position someone is going to shove sticks in front of you. Ask for 2 legged sticks as they can be leaned back or forward to adjust shooting height without repositioning
- bring some warm clothes, it can be really cool in the morning until the sun comes up
- tipping at the end of the hunt is to your discretion, 10% is the norm, distributed as you wish
- unwind, rely on your PH and have fun
The above is geared towards remote areas Chewore, Dande, CAR, Selous not so much SA, Namibia etc.
