My first mare.
Not even kidding. Just as a disclaimer, I do not recommend it. I bought my first horse; a dominant, green, 17 hand mare with NO prior experience. Didn't know how to pick a hoof, let alone saddle and bridle. The amount of times I'd ridden I could count on both hands. My saving grace was that she is boarded, so her care was covered, and that the girl who ran daycamps was happy to help me when she was there.
Originally planned on just leasing for a month to go on trail rides until school. Got attached. Etc, etc. The difference between me and so many people who buy their first 'pretty pony' with no experience is I knew it was a stupid decision and immediately started flooding myself with horse knowledge. I found the HF not long after, and at this point I feel like I'm pretty competent when it comes to horses. I still learn new thins every day, but I know quite a bit at this point and am fairly confident in my horse knowing
The rest of my horsey purchases have been thought through a bit more!
