Applying to vet school isn't exactly like applying to undergraduate schools. I know when I was applying to undergrad, I went and visited all of the schools I wanted to apply to as well as others I was considering. I had solid stats and to be quite frank, I felt pretty sure that I would get in to most of the places I applied. Granted, I didn't apply to any Ivy League schools but still. Anyway, with vet schools, it's a LOT more difficult to get in, as I'm sure you already know. With undergrad, a lot of the admission are really predictable - good GPA, good SATs (within ranges) and you're in, it seems. With vet schools, there are so many other factors (include the wild card) that its so hard to say. I would hold off on touring anywhere until you get to the actual applications. Of the eight (vet) schools I applied to this cycle, I've visited three of them (Colorado State, Iowa State and VA Tech). The first two I visited for undergrad and the last is close enough to me (and my in-state school) that I made the drive. If by some miracle I get accepted to more than one vet school, I'll make the trip out there again regardless to help my decision.
I know there are people on the forum that place a lot of importance on location and feel of the school, and I'm not one of them. I would rather go somewhere like CSU because I like the atmosphere of the place better, but that won't necessarily stop me from turning down another school. For me, with my low GPA, I really can't afford to be choosy and I've said before that if Hell had a vet school and offered me a spot, I'd go 🙄 You may be a more competitive applicant, though, and be able to choose based on location alone. Just depends on the person!
I think the most important thing to do at this stage for you is to do well in your pre-requisite courses (and familiarize yourself with what those are for various schools). Do well in your classes, study for your GRE and do well in that, and evaluate your experiences (do you have animal experience aside from pet ownership, experience with a veterinarian, etc?)
Sorry for the novel!
