Boots and barefoot are fine for some horses, and some footing. And I know it's one of those controversial things that some people will just never agree on.
I continue to shoe my horse.
Boots just don't work in the trails I ride, because we hit a lot of mud and that mud will just suck a boot right off. My money is better-spent on other things, IMO.
@ paintedhorse: I've got a pic of hubby and I at that same rock formation. Do you guys camp in that great equine camp ground just outside the park to the west?
