Things you should be worrying about on an African safari -- how to get better pictures of wildlife, where to pick up cool, authentic souvenirs.
Things you shouldn't be worrying about -- aching feet, dusty lenses, clothes aren't only the wrong fabric, but the wrong color.
When it comes to safaris, the best advice comes from people who've learned the hard way.
We asked pros whose careers have revolved around the bush to share their most practical tips.
1. Break in the right shoes
"Bring shoes with hard rubber soles," advises Nic van Rensburg, biodiversity manager at Lugenda Wilderness Reserve in northern Mozambique.
Having racked more walking safari miles than most, van Rensburg says thorns penetrate soft rubber easily, so hard rubber is far more suitable for bush trekking.
"Wear your shoes in for at least a month before you go on safari so you know they're comfortable," he says.

2. Treat blisters the right way
Blisters are the silent destroyer of many walking trips, but they don't have to be.
If you get a blister, don't pop it, says van Rensburg. That will cause the top layer of skin to rub off and leave the extremely sensitive new skin exposed.
Instead, pierce a threaded needle through one side of the blister and out the other, pulling the needle through so that only thread remains in the blister.
Then, cut the thread so that there's a thread "whisker" on either side of the blister.
The liquid will drain out slowly via the thread, allowing time for the new skin to harden underneath.
3. Leave your black camera bag at home
Travel photojournalist Mark Eveleigh suggests taking a roll-top waterproof bag for camera equipment, to keep out dust and sand.
Color is key.
"Choose one that's light in color, not black," he says.
"Dark bags will heat up your equipment."
4. Bring a shower cap
Not for your head. For additional camera protection.
It should be kept in your camera bag, along with a spare T-shirt.
"A shower cap is perfect for protecting your camera in the rain, and a T-shirt will help keep the dust off your camera when you're driving," says Eveleigh.
