The weather sure has been nice lately, but bringing your yoga mats out into the festering sore that is the 16th and Mission BART plaza?  I'm not sure that's the best idea ever.  The sights, sounds, and smells of a hazmat zone are not exactly the peaceful environs one expects to be immersed in.  And I cannot even imagine what kind of chemical bath you have to give yourself afterwards.
