Knowing which way is up is so overrated.  I learned this after doing a little acroyoga with Tatiana right before class, which made me feel insanely happy, and brave enough to do an entire class of gravity rotations.  We took just a few basic poses and turned them around and around.  But we even did our sun salutations sideways.   Easier for stick figures than fleshy peoples...  we didn't get to everything.  Further explanation will be left to the brave attendees, James, Peter, Declan, Ashley & Sakura! (Comments welcome.)      Add some early American banjo music... not a bad afternoon at all.
