Where're you planning on going to school? Are you going to live in the dorms? In my limited experience, college campuses tend to be rather tolerant places, at least during daylight hours. Dorms can be a little bit scarier -- crazy drunk people and all -- but when I lived in the dorms, the only person I saw have any trouble was the Creepy Promiscuious Bi Guy, and the worst he got was some ->-bleeped-<- talked behind his back.
If you're really worried, you should consider investing in a good pair of steel-toed boots or shoes. Make sure they're comfortable, or you'll never be wearing them when you need them. If you're assaulted, let your assailant get close to you, then aim for the shin with everything you've got. Just don't use them unless it's *absolutely* necessary; the last person I kicked (middle school) was black and blue for more than a month. (He'd grabbed my butt.)
Enjoy college -- is there a GBLT group on campus?
