This photo taken in Buenos Aires at the end of a long night of tangoing reminds me of how I feel after returning from the NZ Tango Festival.  

Lots of tango, little sleep, but all worth it!

Here's the blurb that goes with this photo:

All-night dancers yield to fatigue, but a new, youthful following keeps tango vibrant. "There's something in you that lives and endures," goes a 1932 lyric about the beloved tradition. "Song of Buenos Aires … now grips the world."
