I remember they had a policy of no one over something like 12 on a jumper. Maybe they changed that, because it looks like there are adults on jumpers. When I was little, I was scared to ride a jumper, so there was only a fairly small window that I did.
What the heck!? this was in 2014 but I do not know I would like to go there once the pandemic ends and ride the horse with the blue flower the one that the little boy is riding on I am 14 years old (hold your breath)
