I Love to read all of the horsey story's! I think the greatest way to enjoy horse riding is hacking. Some dressage can be very fullfilling too but it is usually way less relaxing
One thing I feel like saying from the first time I saw it on a photo in this thread; what about the barbwire used in the fencing for the pony's? I know you're not in the position to chance it, but doesn't it scare you? You really don't want to learn the hard way what barbwire can do to pony flesh

One accident can ruin their future as a fully enjoyable riding partner!
