It is a good plan to look at the possiblities, but I wouldn't suggest worrying about it.

I know that the members of my crew that are still in school were looking at options yesterday as a "what if" or roleplaying situation. I was at the same campus when Columbine happened, and those of us of like minds did the same thing then, to. I do the same thing when I've changed jobs, spend more than a few hours at a jobsite, stay in a hotel room, or go out to eat.

Know what you have, know how to use it in any given situation. Improvise, modify, devise, adapt, or fail. Same as any survival situation.

And now back to work, I've gooffed off too much.
