Do some horses hate arenas?

This is the kind of thing that "experts" and "scientists" tell us can't happen. But I personally know a horse who is tense and miserable in the indoor arena and relaxed and happy outside - and we have no idea why. It's the same work...

Horses can have distinct preferences as to what kind of work they enjoy, but where is rarer. It does happen, though. Of course, if your horse won't go down that trail it might not be a preference. It might be they've spotted something you haven't...

Some horses, too, simply hate working in arenas because they've spent far too long doing the same boring things. I'll talk a bit more about that tomorrow.
