If you have to take it and hide the fact that you are taking it and if it is going on or in any places at all where it is not allowed, you are breaking the law.
This isn't strictly true. You may feel the need to hide it, and hide the fact that you're taking it, without breaking any laws at all. Most of us hide the fact that we're taking a gun with us every day, though we're breaking no laws. Anyone who doesn't open-carry does so.
Second, there are many places where guns are "not allowed" by various powers-that-be, wherein that prohibition is not backed up by any law. If I carry a gun in a local amusement park it is "not allowed" by park rules, but not prohibited by state law, so my risks are limited to being asked to leave.
You guys have obviously never seen true evil, because a man who has will never allow himself to be unarmed.
None of us would advocate being "unarmed." But few of us would agree that simply not having a
firearm with you makes you UNARMED. There's lots of tools in the toolbox (some already mentioned here) and some are more feasible in some circumstances than others. Many of us spend large portions of every day or every week in buildings, locations, sites, or even whole states where having a firearm on hand at all times is unlawful and/or impossible. We cannot, however, consider ourselves "unarmed." "Unarmed' is a
mindset failure, not a toolset limitation.
I absolutely agree that you must weight the likelihood of violent altercation (probably slim in general) in which only a firearm would avail you (slimmer yet), modified by your heightened practices of situational awareness (to avoid danger) and your secondary defensive capabilities (what other tools in the toolbox?) -- against the danger presented by discovery (more likely in a directed group traveling and lodging together) and censure by your institution (serious repercussions for loss of your educational investment and loss of future livelihood).
You can't carry daily right now due to your state's limitations. By what means do you avoid trouble and prepare to defend yourself during your daily life? How do you foresee those means not being sufficient during your planned trip? If you will be exposed to heightened risks during this trip, what can you do to step up your capabilities without risking your whole career?
