That sounds about right. I have a 2008 filly that hasn't been registered yet, I have her papers and need to get around to sending them in. She is a very well behaved 3 year old we happened upon that has been started under saddle lightly. We have been getting her used to us and will be starting her more under saddle about midsummer.
I wish I could see some pics of the sire and dam and have searched everywhere but nothing.
