I use some techniques to hide my passport, credit cards and cash when visiting some places when I travel. These items can allow you to visit risky places without the fear of losing your important valuables. Most tourists spots are Okay but there are some places that you may be unsure about like here in St Lucia, where you have the potential to be held up at gunpoint or perhaps pickpocketed. You want to look like you are not carrying anything and not be a target.
If you do nothing else, you should at least have a passport holder that hangs around your neck that can also hold your credit cards.
A belt that allows you to store folded paper money is a good way of carrying a lot of cash.
Leather wrist and ankle bracelets can easily be hidden underneath socks or long sleeve shirts and at the same time will allow fairly convenient access to your cash.
NEVER enter passwords when using public WiFi networks. It is too easy to download software to see the keyboard clicks of others on the same network. Make sure that you have different passwords for every different website you login on and don't use part of your email address for the password.
I'm off today to catch another minibus, this time to Soufriere.
