Check out this bunch of dancing feet I collected during just a couple of hours at a milonga in Buenos Aires in February. The Argentines really dress up when they go out to dance. No need for signs reminding patrons not to show up with ball caps or sneakers or ripped jeans there.

Since my return from the southern hemisphere, I've been trying to get out dancing more with a friend of mine. I have yet to try the tango, but I love salsa, merengue, bachata -- all that good Latin music that practically challenges you NOT to get moving and have a blast.

As long as it's not a couple-y event and people ask you to dance, it's a lot of fun. I'm not the greatest dancer, but I have fun trying. And by the end of the evening I feel like I've gotten the equivalent of three gym workouts of exercise. Just listening to the music and watching the really good couples dance can take you miles away from workday stress.
