One of the things I struggle with is thinking I am good to go on day one, when I know I am not. This has cost me a few FUBARS over the years. Especially if on malaria meds. I get completely ruined for 2-3 days by the air travel, not all do but it affects me greatly. So if you are at all prone to jet lag, try to resist the temptation to do much shooting right off. You might save yourself time, embarrassment and money. If you have something, a specific animal that keeps you awake nights, try to avoid shooting it on your first day. Either you will mess it up, as I have done a couple of times, or even if you get it and alls well, you will feel like you cheated yourself by getting your top critter out of the way too soon. Sometimes the PH likes to have the client take that special critter right off, as it takes some heat off of him. Its your safari, not his. Do it the way you want.
