Go for it, Egglady ....you will enjoy it!!
We are just breaking one of our young Dales ponies to harness at the moment, and have a young Fell filly too, to break. Have done a friends outgrown Welsh Section A too, and will be having him back to do more work on him. Keep getting enquiries from people who want to learn to drive, but we are busy with our own ponies, and have to fit it in around that.
