Nature Walk?

There is a path around our subdivision that I enjoy walking a few times a week. Most of it is lined with trees. There's a ridiculous number of rabbits. And occasionally other wildlife to be seen.

There are, however, some unavoidable reminders that this little patch of nature is smack dab in the middle of human civilization...

I can think of no plausible explanation for bringing a shopping cart halfway around this 4k loop and then leaving it. But I suppose someone had a reason. By the looks of the mangled lower corner, the cart had a rough ride getting here.
