I carry a pocket knife most everywhere.
When I'm in my car, I usually have at the least a wooden practice sword within easy reach, if not this:
The handle is a little different, but the blade is basically the same. I think I may have an older model or something.
I plan on getting a concealed carry permit once I can afford a handgun (meaning...once I've held a job for a couple months). Considering a revolver, haven't really given the type of gun all that much thought.
For anyone that is wondering why I would carry a gun, there are many simple reasons:
1. We don't have "good" gun control in this country. If someone wants a gun, they will get one. Legally or otherwise.
2. I live in Houston. We have a fantastic crime rate. By fantastic, I mean high. My parents live in a "good" neighborhood, and there have been at least two murders (with a firearm) near here within the last year or two. That I know of. By near, I mean within a mile. My car was broken in to at my parents house a couple of weeks ago. My parents' house has been broken into at least twice thus far. Did I mention we aren't in what is considered a bad neighborhood?
3. Though the campus has a no-gun policy, meaning that it wouldn't have mattered if I did have one, I graduated from Virginia Tech this last May. That was a big reminder to me that it could happen anywhere, at any time. Am I paranoid? You're damn right I am. I still find myself checking for easiest ways to barricade rooms or escape from rooms as I go about my day. I don't want any sympathy for any of it, I was lucky, I was off-campus at the time. This is merely a further bit of explanation.
Like has already been mentioned, I'd rather have a gun for years and never have to use it, than need it for a brief moment and not have it.
