Maybe the flashy horse in #5 has loose morals, which would qualify it as a loose horse. :wink:
Regarding #4, a mule or two contaminating the picture could be regarded as just a prop, much like having a rosebush or corral fence in the photo. This doesn't take away from the fact there are loose horses involved.
No. 5 doesn't qualify. It isn't loose...you are right, Leanin' H.
Edited to add:
But this contest is just for fun, after all,
As far as the mule in the other picture, that's not a problem as
far as I'm concerned.
