horizon pictures

I posted an ad asking for pictures of the horizon under the "wanted" section on Portland's craigslist (I said exactly what I said in the post below this one). Four people emailed me within 24 hours, and these are their images. I think it would be cool to put that same ad on every city's craigslist site and see how many I can get from all over the world. I'd like to make something out of them, but I'm not sure what yet...
