She has been riding every fortnight for about 5 years. I know nowt about riding, but I assume she's doing OK as she seems to be sitting the right way up on the beast and doesn't fall off 
She moved from her first stables earlier this year to be with her friend. The new place is great for hands-on experience with the ponies - she gets to tack up, groom, clear shit (woopdewoop!) and various other jobs. problem is the 'various other jobs' appear to include weeding the garden around the stable and chopping wood for the owner's rayburn
. But DD would be fine with that if the owner wasn't a bit of a mardy cow.
The local college has a riding school that has a good reputation for teaching children to ride. It's more expensive and probably more formal but DD is quite interested to give it a go. But there is no way she'd get to help out with the horses - you pay for that priviledge it seems!
So.... option 1 stay where she is, carry on with the stable work and grumpy owner. Option 2, move to a better riding school but miss out on the grooming etc.
BTW she is considering training as a physio and then later specialising in equine physio so hands-one with horses is potentially quite useful.
DD is torn. I am ignorant. Please help.
