While this dilapidated barn may seem abandoned, it is actually a fully-functioning barn for the property where it lives, but it’s weathered look really makes you think it’s no longer used. The next shot is of a barn that is no longer used as anything except for temporary shelter for the horses pasturing in the same field where it lives.
And my final picture for this challenge is one I blogged last year for another challenge (carefree). I think this expresses the other well-known meaning of abandoned perfectly.
