Can tell you how NOT to learn Spanish--use one of those electronic translators. Tried it in Cartagena, and the locals laughed their ass off while I was trying to type words into my translator. The hooker that propositioned me in Santa Marta spoke the best English during my trip to Colombia. I personally recommend duolingo, but have been stuck at the same proficiency level for 3 months.
