Welcome, and thanks for sharing. I also started riding at 50. Took lessons for almost 2 years prior to getting 2 horses. I've had a love for westerns and horses since I was a little girl. I still have a long way to go. Although I only plan on doing trail riding, I love watching some of the dressage classes and always want to learn more.
This is a good place to learn. I do most of my research here when there's something my instructor is trying to teach me that I don't really understand. People here is full of knowledge and don't mind sharing it with you when they understand what you're asking. You may get different opinions sometimes, but no 2 horses are exactly the same. What works with 1 may not always work with the other.
