How to learn tango dancing?

We have been taking dancing lessons for several years now and it has been a lot of fun -- we are a couple with literally no background in any form of dance so it was a challenge to learn to move our bodies. We have tried mostly ballroom dancing and Lorena has taken some bellydancing lessons but one dance that we have not tried yet is tango. While it is one of the most beautiful dances, it is also somewhat difficult to pull off because the movements are geometrically precise. This is a great video that explains some of the moves and how you can also start learning this passionate dance from Argentina.
