Yeah, she was definately a CHUNK. LOL! Her tail came out of a big dimple in her butt. You could tell she hadn't done anything other than eat and be a pasture ornament in quite some time. This mare was probably about the same height as Pony. I didn't get too close to her coz she didn't seem to appreciate the company, but I think her withers would've been slightly below boob level on me ;o) and I'm 5'7".
My pony was heavier in this pic too.... looks even more like the other mare.
