Another rider here. I grew up on a TB breeding farm and did eventing until I started nursing school. My favorite thing about being a horse person is laughing when everyone asks "aren't saltwater fish expensive?" Let's see Horse $10,000+, Feed $150/month, Shoes $100+/every 6 weeks, and the list goes on. Then you buy a truck and trailer, start showing, spend every weekend driving around the country, etc. Yeah, I don't think the fish can ever seem all that expensive to me.
I will finish school in December and hopefully then I will have the time to get a couple of young ones to start. I get to go out and ride for other people from time to time, but it's just not the same as having a horse that's "mine".
