After all these years, I kinda like the smell (yeah, I know, that's weird. In my own defense, I think pony pee smells awful.) But, after all, all the ponies eat is God's own green grass and oats, it's not like they eat meat or anything . . .
It's not the worst thing, in an open area. I love the mixed smells of barns too. Closed in a tight space, it can be a bit lethal!
