No-mans land

This i don't know, what it symbolizes. A pole sorts erected. To it were tied a number of used water bottles, telling what God knows.

Captured it while coming back from the TN-Pondy border. Usually associated with movies like Robinson Crusoe in a no-mans land.

Could not get a clue as to why it were there but anyways made for a good shot, so just took it. Sorry, but could not zoom as i was riding the bike. So you would have to zoom your eyes a bit to get the clear picture.

Any guesses. Just get brainy and add a comment.
