A quick question - are you assuming you will be on foot with you BOB? I have a "get back home bag" that is extremely light and would allow me to get home it has 2-3 days of worth of supplies – it grows a little in the winter.

However, my BOB is large and heavy it assumes I will be leaving by means other than my feet – I’d be in a truck, boat or plane. This is assuming I could bug out which in all likely hood, it would be near impossible.
