I think it appears to be at her Mum’s house. It’s an expensive sport. Good horses can cost a lot, I don’t know much about her particular horses but she proclaims them to be “top class”, maybe they are and she just can’t ride them. She has shown herself buying “the best” saddles, bits & other equipment, she bought a horse lorry, there are obviously running costs with that, she put in a sand school at her Mother’s house but maybe her Mum paid for that. Then you have vets fees, farriers, feed, lessons (she might want to get extra) and then you have equipment for the rider, even though she begged to get her Vivendi gear, it all adds up. I think it’s just another thing where she thinks she can show off her “wealth” that we can see she doesn’t have. As I said before she’s “all the gear & no idea and definitely fur poncho and no knickers”.
