OBG, I am enjoying the discussion.

I adopted the general 72-hour idea for a BOB from some of the first discussions I read, but I have no investment in such a rule beyond saying it makes sense to me as a planning guideline.

Granted a BOB for each of us will be individual in the sense that we have preferences, varying medication needs, and wear different sizes of clothing, etc.

However, if we start with the Rule of Threes for survival [3 minutes without air, 3 hours without shelter, 3 days without water, and 3 weeks without food] as a sensible BOB planning guideline, and add in the fact that we are supposed to cover some distance while carrying the thing [bugging out] then our BOB contents are going to fall into categories that are not very individual.

But I have been properly corrected before.

What do you think?
