I have to admit, I'm a little taken aback by the "It's impossible!" thinking of some people in this group. It's so intense that we now have a seperate thread devoted solely to slamming the OP?! Come on!
I agree, such a feat is not impossible; but the question is: is this a course of action that one should plan for?
Regardless of whether we are talking about primary or back-up plans, an important aspect of preparedness, in my mind, is evaluating risks and understanding what scenarios make the most sense to prepare for.
One of the things I really I like about ETS is that it puts realistic bounds on preparedness and survival. We typically don't look at unrealistic or improbable events (i.e.,
this is not a survivalist site). We don't plan for apocalypses, alien invasions or the fall of civilization. This isn't a forum to figure out how to live in a Mad Max wasteland.
But, even within the described purpose of the Natural Disasters & Large-Scale Emergencies sub-forum, I simply cannot think of any reasonable scenario where a family in the US or Canada would have to undertake a 400 mile evacuation by foot.
Maybe I'm wrong, but I simply cannot understand how planning for this either makes sense or fits with the confines of ETS.
