What is the MOST read book on the subway?

...i have NO idea. :]

Now that i kinda consider myself a 'connoisseur' of the subway -- hey! i gave someone directions today!? 

Okay, I'm not. 
I'm totally lying.

BUT, i can tell you that in the past week, i've sat next to TWO different folks reading the 'Great Gatsby'. Being the nosy person i am, i started [reading] this guys book while on my journey to the city today and realized how VISUALLY written this book is.

Captivated, i knew i wanted to draw a quote from the book. This ^^ grabbed my attention and now, here lies today's 'nightly doodle'.
