There is a chance to be robbed almost everywhere and i heard this stories even for the developed countries like France and Spain. Kipnapp happens too but I think this is more common in the americas.
I mert an italian in amr de plata, argentina where he was studying spanish and i was serving tables (in exchange for a bed every night while waiting for my new passport to arrive) we share some of our travel experience. I thought i had it bad that I was mugged in Dakar by 2 guys which left me paranoid for a few weeks but his story, if it happended to me might have send me home.
Caracas is one of the few dangerous cities and on an overnight bus to Bogota, Colombia, their bus was hijack by robbers. It was christmas season and many colombians were going home with their hard-earned money and he was the only foreigner onboard. Hijackers had guns and even fired shots while in the bus. The took his money and flung his towel (which he was using as a blanket ) over his face. He said it is even more terrifying not to be able to see what is going on.. every sound makes him jumpt out of his skin. the ordeal last for about an hour before the robbers took off with everyone's possessions. Although no harm came to them, it was scary and many of the colombians were crying their eyes out for losing all their money.
Mexico City also has a reputation for kipnapping foeigners for their credit cards and pin number. I think there was once a program on Nat geo about 2 British women who were kinapped for a few days while they cleaned out their bank account.
dont be too paranoid though.. they are also good people out there and sometimes they are some things that are not within our control
as fr your photos... good luck

I was losing steam with sorting them out because they are so many.With this thread to share my experience and photos, its making me more excited to go through them and sort out my favourites.
