Yes, we are serious about the cold room.  Our agenda includes a lot of interactive practice which means you’ll be up and moving around.  Better to be cool in the morning than far too hot in the afternoon.  With our energy we might be sweating while you end up shivering without a sweater or light coat.  We suggest that women do not wear skirts or dresses for this reason.  We ask that you please plan accordingly as we will not increase the room temperature if you’re chilly.
