Can I make a suggestion? You should check out College of the Ozarks. It's just south of Branson, MO, and it's a work-study school - every student works 15 hours a week at an on-campus work station, and in exchange you get free tuition. There's a pre-vet track or you can major in Animal Science (that's what I've done). You can graduate without owing a thing (I'm about to), and you can even work through the summer to pay for your room and board. It's very competitive to get in though, and it's based largely on financial need, so if you want to get in, you need to start applying now. It's not big on the equine aspect, but if you're into dairy cattle, we have our own dairy, as well as our own beef farm (and hog farm, and processing plant), so there's a LOT of cattle involved in classes (I don't care for cattle, and I'm SO SICK of hearing about cows all the time...). The professors are AMAZING - I'm going to miss them so much. If you can get into there, you can get into veterinary school without owing anything for your undergraduate degree. There are several other work-study colleges in the nation, although CofO is the only one with an agriculture program that's any decent.
Anyway - if that interests you, College of the Ozarks, Hard Work you.
