An interesting Interview

Found this short interview with Chuck Palahnuik (link).
What I found interesting (and why I am sharing it) is the description of the creative process. Chuck works with a writers group, reads aloud his works in progress and claims to spend time in hospital waiting rooms to work.

I would have to say a hospital waiting room does not leap out at me as the most obvious choice for inspiration. But I do agree that certain locations are more conducive to the writing process. For me, its airports. Doesn't seem to matter which airport, but I always make a point of traveling with a note pad, scribbling down thoughts and ideas. Perhaps it the because my phone is off and traveling for me (I'm usually on business and going solo) is a shuttle between office, hotel and airport. Usually the airport departure lounge is my only space where I'm not distracted, I don't have to be anywhere else and for a few minutes I'm 'off the grid' as the saying goes.
I can collect my thoughts and ideas.

So my question for the Bubba's out there, literary or otherwise, do you have a creative zone? Is a mind state or building or a time of year?
