Mena was the first thing I thought of when I saw Clinton and Columbia in the same sentence.
I do have to clarify that post, though: as I've reread some of those early threads, they were more about Clinton's dealings in Arkansas while cocaine was being smuggled into Mena from Colombia.
An absolutely sordid story. Some of the sworn testimony at the links (that still work -- get 'em while you can) reads like any number of thrillers that Hollywood produced over the next 30 years.
