I am fortunate that I live in a state where publicly funded colleges are not allowed to ban the carry of firearms by people who are licensed to do so. A fairly recent law, and long overdue IMO.

As far as being prepared to defend myself, I consider it no different than being prepared to build a fire or purify water. I carry an RSK and a handgun, as well as pepper spray (while jogging.) I keep myself in reasonable shape and try to be aware of my surroundings at all times.
