This is just a personal thought, but what location do you consider to be your favorite place to read graphic novels or books of any sorts? I can mention that I have just about two spots that I always find myself reading comfortably, as my mind zones into the world of the fiction.
One: My bed with the sun shining into my room as a natural light.
Two: Moving subway car. Since my commute is often an 45 minutes to an hour. If I had my iPad, then I am set.
Without a doubt, you can read anywhere you choose, but definitely places where you can find confort, ususally ends with a stack of manga being read. As Spring hits this hemisphere, how about reading outside spots?
