"When you begin to question your dream, awakening will not be far away."
-Sri Nisargadatta Maharaj
You are brave (or dedicated)! That is one scuzzy-looking airport carpet.
I did not notice.I do however have great respect for yoga in awkward spaces. Somehow the benefit is even greater than in a dedicated yoga place.(My other favorite thing at the airport is the chapel. The one in Albany actually has a meditation room. And I've heard that San Francisco has a yoga room!).
I checked out the SFO yoga room. It's within steps of TSA security, but worlds apart. Just keep your shoes off, and head on in. Wonderfully, the icon/symbol for the room is a figure in padmasana, or thereabouts.
There's a yoga club at my office that's met every lunch hour for years in a conference room to put on a video.
