What an incredible fly-thru! For $13 I couldn't resist - just finished downloading. I even dug the nautwalk.wmv file out of my browser temp folder and saved it to my Products Purchased ReadMe folder (hope you don't mind). Just incredible - The fly-thru detail holds up even in full-screen mode! I hope you guys make a ton of sales from this, they'll all be happy customers. Happy 4th, indeed!
