In terms of Return on Investment, which is the only realistic way of looking at it....
It should take approx. 1 year to make your return back. It could happen a bit sooner, if you promote the site more than I did.

Why would someone stay home and sit back and make "x" amount, when they can make 3x "x" traveling around the country doing what you enjoy?
Life is all about options and which ones you take.

This was very good for me, for the past year, but now it could be good for someone else, because I won't have time to work it like I could if I was home all year.
