My experience this morning.
I awake to rustling above my head; white empty ceiling vanished, replaced by leafy branches above my head; three young squirrels chasing each other from branch to branch. My organic air conditioning aka the wind sends a constant flow of air through my tent. A singing robin acts as my organic alarm clock waking me up in the morning. The interior decorating in my ceiling has changed from green to yellow-gold. My carpet is now a rich mass of fallen Autumn leaves. I shave, stretch, and then leave behind my tent, to go to work.
