From the "marketing department": When sending this audio file to a friend, please understand they will probably choke when they see it's over 3 hours long and toss it into the "later f'r you" bin.
I heavily suggest you send it with a plea to have them promise you, at least give it to the 8:05 mark to make an informed decision whether or not to continue to the end. And make sure they understand it's a book, and does NOT have to be digested in one sitting; break up the 3 hours as need be.
Keep in mind how important this is from the standpoint, AK has a plan to get over 200k copies into every mailbox in New Orleans real soon. Steem on, people! We are helping him fund this effort, I think.
