One of the things that I've been contemplating for an interim boarding situation is putting Gwyn into training board with a dressage or eventing trainer. I've reached a point with her where her progress is beyond my ability to really solidify without either guidance or someone else sitting in the saddle.
I've been doing a ton of research online to find potentially suitable places to send her for training and I'm compiling a list here so it's all accessible from one spot so I don't have to search over and over again.
