I can't remember if I've posted this before or not, but essentially I totally agree and have done this in practice for two years. I travel at least one weekend a month and as a result I have a pretty good little kit put together. I virtually always bring rain wear, a wool sweater, and in the winter I add long underwear. Now I also keep a space blanket, knife, and fire making tools in the same bag, sometimes a gun. I look at my weekend bag as my bugout bag too. It wouldn't suit me very well if I end up in the deep wilderness, I admit, but I could rough a night out during 8 or so months of the year. In the winter I should try and keep a sleeping bag w/the go bag or bug out bag. I don't call it a bug out bag, I prefer go bag or ditch bag, as it isn't geared towards wilderness survival like it seems most BOBs are these days.
