Here is my edit. I took a little different take on it. But you could just as easily crop the image to get rid of the stuff.
I too got rid of the road as well as the mail boxes and what looks like a driveway/sidewalk right behind the dog.
Damn lol he posted his first while I was doing my edit. I also like the road being gone but if your going to get rid of the road get rid of the mailboxes too they dont look right in the middle of a field.
The mailboxes look fine. For me it looks like a road that's there but covered my a high curb or is a little slanted. And what I and probably most of us did was use the clone tool in Photoshop. You select the Clone Stamp Tool press and hold ALT and with your mouse select the part of the picture you want to sample and click then let go and draw over what you don't want. Takes a bit of practice to make it look natural but its worth it.
Yeah, I don't like the cropped looked (tried that first). I tried playing around with the clone tool.. *sigh*. I have a lap top (so a touch pad, no mouse) and really unsteady hands. Oh yeah, and NO patience. The garbage can doesn't bother me as much now.
