I think that's a good idea. You definitely never want to talk just over email. People have a tendency to not be truthful in what they are saying. If you get a hold of the guy and can actually talk to him, that might be better.
But I think overall you should just continue looking for more people. Having your horse move that kind of distance is a problem if you want to stay in contact or at least visit the horse. It's a very plausible reason too.
