Actually, I would love to have a horse and have wanted one since I was little (who hasn't here though? Haha) but I'm worried my inexperience would make it nervous or unhappy. If it counts for anything, my mom grew up raising horses so she's experienced but not in the shape to ride. Also, in our situation, we actually have taken account of boarding and vet bills as well as the cost of just a horse, and we wouldn't be able to board it at the lesson school for several reasons: high cost, unavailability, and the fact that she keeps up to four horses in <1 acre lots. There are other cheaper boarding stables available nearby. I have another year of high school left (no, I was not held back) and I may go to school in state (just for money reasons, I'd rather go to Duke).
This may be a little off topic, but my parents are also considering this because I've had a rough year and need something to keep myself busy and look after.
Thank you all for the great replies!
