Do You KNOW what June 16th is?

It's "BUY A REAL BOOK FROM A REAL BOOKSTORE DAY":

I'm totally doing this.
This is a cause I will gladly and wholeheartedly support.

Are you in?
Get your friends or family together and go on a bookstore crawl.
New and used. All Saturday long. Such a fun idea, no?

What book will you buy on June 16th?
