I dunno, still seems to me it's two different concepts. Bug out Bag is really for when TSHTF situations. If you have time to prepare it, then you'd naturally want to pack all you could in the time allowed. When you've got no time and need to skeedaddle, the cart concept just seems to be counterproductive. I like the idea, it's the same premise I subscribe to for having well packed grub and gear boxes in the garage so that in 5 minutes or less I can load up the rig with enough stuff for me and the wife to get by reasonably comfortably out in the boonies for a month if need be, It just isn't the same as a BOB event.

Maybe I am just splitting hairs. The bug-out concept can encompass more than just having to run for you life in 30 seconds to include extended provisioning and transport over more ideal terrain than having to jump burning debris piles, ford streams, evade threats, and such. I was always a bit more focused on the mobility side of things and taking care of the other business when time and conditions would allow. Not all bug-outs are that extreme I reckon.
