What
you have to remember is that the desert - any true desert - is an amazingly
beautiful, amazingly spiritual place. It's also an extremely dangerous place,
and every year we have several cases where people, usually tourists have
serious problems in the desert and have to be rescued. And if people just use a
bit of common sense, and follow a few basic rules for survival, this could so
easily be avoided.

I
think the first thing is, if you decide to go into the desert for whatever
reason, just let one or two people know where and when you're going, and when
you expect to get back. That way if something does go wrong, people will know
where to start looking. There's not really much chance of finding you if we
don't where to look. And never ever go into the desert alone. As for things you
should take, well there's just one word which is water. You must be sure to
take plenty of water, and by plenty, I mean at least two litres per person per
day. In the desert there really is no such thing as too much water. And
definitely no alcohol, not even a cold beer - that will dry you out and make
you even thirstier. Check you've enough spare fuel for your vehicle - at least
twenty litres. As for the equipment you should take, well, of course, a map,
and a compass ... preferably a couple of maps, and be sure to take a small
first-aid kit with a pair of scissors, some bandages and a sharp knife. And
take some matches so you can start a fire if need be.

You
can experience extremes of climate in the desert, so you'll need to have lots
of sun screen if you don't want a bad case of sunburn. On the other hand the
temperature drops dramatically at night Actually, more people die from the cold
than from the heat, and very often people don't take any warm clothes to put on
at night... but you'll need them ...
