My planned response to what?

The situation will dictate the strategy. Approaching the issue any other way (IMO) is fatally flawed.
In the end each individual is going to have to make a (hopefully enlightened) decision that fits their particular scenario. The right decision for me might not be the same as my neighbor.
Yes, and when people start preparing for an event they tend to give one option preference and prepare for that option much more than other options.
Sometimes it is to the point where they actually lose the secondary option.
One of the results might be that they are be totally stocked to survive a year in their home but not have any real plans or equipment to evacuate if they had to, or they might be the exact opposite.
Hopefully most of us have a sense of balance and keep more than one option open.
