If you haven't already been there, check out Simba tango's latest post, 'Baldosa'. (Link on the right.) A dramatic demonstration by Ricardo Viquiera and Fish of just how little space you need for a good dance.
Fish is a wonderful dancer, and completely fearless too. I assume she's Fish Pez, and remember this video of her a few years ago dancing Candombe Milongon with Ruben Terbalca.
