Carrying cash. Try a money clip
Let me chip in on my experience carrying cash. Someone of one of these forums suggested carrying a money clip instead of a wallet. Turns out, it's a great idea. At home, I carry a wallet with various cards and driver's license inside, but these are unnecessary when abroad and I leave my regular wallet and its contents at home. When I monger, I only carry a money clip on the street.
It's harder to pick a money clip out of your from pocket instead of a wallet. You can also fold up a color photocopy of your passport if you like and keep in the money clip with your credit cards. I carry my US Passport card instead, along with my daily cash allotment and my debit card only if I need to make an ATM withdrawal.
I also have a undergarment money belt to wear "in transit", but I don't carry it around when I get to my destination. It's awkward enough just to access at the airport, much less in a bar or on the street. Once at my destination, I only carry around the cash I plan to spend for the day (or evening) and leave the rest in the safe at the hotel. I also found a plastic case to carry my condoms in. You don't want to be crushing those things, do you? I use a Nintendo Gameboy game case, which you can find on Ebay. Its perfect for a large size condom (or 2) and a little packet of lube thrown in. That goes in the other pocket. I also got one of those plastic "squeeze" coin purses to carry in places like Thailand, where specific coins are important to keep handy. Maybe not such a concern in Colombia, where small denomination coins don't buy squat. But, it sure helped to organize coins for when you are using a public toilet or "baht bus" in Pattaya. So consider getting one of those in places where coins are actually useful to the monger.
