My wife and I play that game sometimes while driving.."o.k. - emp hits NOW, what would you do?...". We still have not decided whether bugging out, or bugging in would be best, but I think it will actually be affected by whatever happened that required us to "bug"anywhere. Either way we are sort of prepared (can you really ever be totally prepared for the unknown?). The biggest worry for us is clean water since we live in the desert (and of course zombies and bandits, which we are prepared for!). We also need to plan for for medical training. If it really is a SHTF situation, medical needs will have to be taken care of by ourselves I think.
I am also finding that rotating our fuel storage is more of a hassle than I origninally thought it would be.
Fun things to think about though, and great justification for that new piece of gear!
