Nah, he was nice. I asked him to move off the range and he did.
Some horses are surly and stubborn with strangers. ;-)
Some are surly and stubborn with people they know quite well. I've known several like that. Been bitten and stepped on too.
But the key word is "was". I'm sure he's still a nice horse... for how long it's hard to say, since I didn't look in his mouth, and couldn't tell much if I had. But, no gray in his coat. But he looked a little skinny and awful tired, maybe he just needed a day off from all the loud noises in his pasture. :)
