I spent an hour today comatose on the grass, guarded from the unusually warm sun by a large group of pine trees. It still amazes me after three years of working in San Francisco how a small square of green can calm and tranquilize the senses, even as the rest of civilization continues bustling onwards on every side of the oasis. The natural recharge just reset my body and mind and spirit in a much needed way and reminded me of the majesty of escape and necessity of nature in urban areas.
