I've had a couple of freebies over the years - two Standardbred mares & a crossbred gelding!
My first horse was one - Bailey. She was four, green broke and I was a 16yo who only knew the basics of horse care... had been riding since 11 but not taught the "behind the scenes" as much as I thought - was a difficult start to horse ownership, but I owned her for 7 years and she taught me a lot - mostly what not to do!
My other was a beautiful mare, April who was left in a paddock by her owner & neglected. I looked after her and the property owner gifted her to me when they left the city. She was with me up until 2007 when I sold her as she had developed arthritis and I wanted her to slow down in work and teach someone else what she had me since she deserved it. She was put to sleep 1.5yrs ago and I miss her every day. She was super special, and still one of my most favourite horses.
My gelding JD was 3/4 TB, 1/4 Cleveland Bay. I don't have any photos of him sadly. I had him for two months, but we didn't click well under saddle and so he was rehomed with a lovely family.
