You do realize print is dead, right?
You're wasting a mint getting your shitty little book printed and bound, go the e-book route and blow your hard earned dough on hookers, bubbly and blow like the rest of us smart guys.
Now, I know what you're going to say...
"Its a river guide, and people can't take an e-book on the river"
Look guy, I didn't get all these hookers, bubbly, and blow by being stupid, so just for you I spent like 4 minutes of my valuable time inventing a magical device by which people can convert ones and zeros into a's b's and c's. What's more amazing is the fact that Ive also enabled that magical device to scribble those a's b's and c's onto paper, which your customers can take with them on the river, so they don't get lost.
Stick with me dude, I'll make you lower middle class, or upper lower class in no time.
Love you in the mouth,
