The idea of a bob and a ghb really depends on what your situation is. For me, I travel the whole state of colorado on a weekly basis, so I carry a bag with me in the car that has the supplies I might need for weeks out in the field, in case I need to make it homes to Colorado springs from say montrose.

Obviously one can not carry enough supplies to make it that far on foot, so the core of what I carry is knowledge. In every location I go, I think about how would I get home from here. And in some circumstances the answer is that I would not even try to cross the Rockies until the spring/summer snow melt. So essentially I'm prepared to bug in in far off locations until I think its possible to try and make it home to my family who hopefully will be bugged in at home.

I also find it easier to prep just one bag, rather than 2,3,4 bags for different scenarios. I've even packed it in my luggage when traveling by plane to other locations when I felt really paranoid.
