I an attorney who travels quite a bit. I am from the Washington, DC area and have an apartment on the beach in Cartagena Colombia. I can speak some fractured Spanish as well as some French and German having lived in Europe for seven years. You should have a good time here as long as you are not a Secret Service Agent!
Having lived abroad for years, I try to counteract the "Ugly American" image and try to leave a positive footprint whenever possible or at least have some self-awareness. (no fannie packs!)
