Query: Excellent Ideas

I think Mary McDonald's book is full of sound and useful advice. I have boarded horses, bought and sold horses, and taught riding lessons off and on for 20 years. Recently I decided to begin teaching lessons again, having taken about 8 years off. I referred to this book for ideas on organizing, planning and implementing my new riding program. I borrowed from it liberally and feel much more goal-directed and organized than in the past. I recommend this book as a starting point for anyone considering becoming involved in the horse business.
