Columbia is a fabulous place to visit if you are street smart. If you aren't go to Orlando. And once you get there don't do anything stupid. It is easy to be forgiven for stupidity in the US. It is easy to be dead for stupidity in Columbia.
I was a contributor to the lonely planet South America in the mid 80's it is a good guide.
The columbian people are some of the happiest most outgoing friendly people in the world, at the same time their high emotional level can turn into a fist fight very quickly.
