i'm pretty sure it's a private company because it ONLY runs at the start and end of breaks (small exception: they were running them for the open house and if you do an overnight visit). i'm not sure how it'll work in the fall with everyone bringing a ton of stuff, but i would think it would be easier to get your own transportation.
my fam is dropping me off, so we're gonna be renting a car (read: a large suv). if you're just going by yourself though or with some friends, you can't rent a car, but i used At Your Service Limo (
At Your Service Limo - Animated Intro) this past weekend when i visited campus. it was pretty affordable and it looks like they have larger cars for transporting lots of stuff...
hope that helps
