You can borrow Care and Training of the Trotter and Pacer, published by the US Trotting Association from our library (Memorabilia and History also) at the Bendigo Harness Racing Club if you like?
It is a great way to find useful info...also I'm sure that the staff at the Harness Racing School at Bendigo would be happy to help.
