Oh nonsense. Travelled around Cuba (including roaming Havana at night!), Colombia, Puerto Rico (by publico), Venezuela, Costa Rica and many more countries both Latin and un-Latin as a girl on my own. It's experience and common sense, and you quickly develop a sense of intuition. I travelled through 20 countries on my own when I was 18 (starting in Mexico) then decided to first hit Africa at 20.
Africa gets a lot of bad press; many regions are (or were) amazingly safe. I spent some time in Kenya long ago, and I was blown away not only by the diversity but by people's friendliness - from Kikuyu farmers to the Masai, Indian truck drivers to Arabs on the island of Lamu. Of course, I spent most of my time in the bush, and the wilderness is always safer than civilization. Plus I was seldom really alone.
I spent a little in Mexico alone, and I knew very little Spanish. However, I'm a guy, and I spent most of my time in a remote area where people were really friendly.
But times have changed. The corporate war against terrorism has stirred things up in a lot of countries. I think even a lot of developed nations are becoming more dangerous as they descend into economic and political chaos.
Ironically, I was almost killed by some guys who attacked me on my way to work right here in Seattle. I would NEVER tell a foreign visitor that Seattle's a safe city. There are neighborhoods that are very dangerous, and gangs of U.S. soldiers from Fort Lewis - America's most notoriously troubled military base - were recently assaulting even groups of people right in Seattle's university district. To put it another way, Seattle's safe 95% of the time, as long as you use a little common sense. But there are no guarantees.
I'm also struck by the number of visibly wacko people here in the U.S.; I don't recall seeing those kinds of people in Mexico or Kenya. There were poor people, but they weren't ordinarily violent or mental.
People have warned me that it's dangerous for a gringo to travel alone in most parts of South America. I suspect that will change as Latin economies continue to improve.
If I ever visit Cali, I'll probably hire DJ Ara as a bodyguard. Hopefully, I'll only need protection from all those salseras.
