Bugging out is a helluva topic. The whole concept is to leave your troubles behind and wait for the worst to pass. The reality is that you can't carry enough with you to last without an 18 wheeler. You either have to stay in place or go to somewhere that you have positioned enough supplies to last. Bugging out to a place you have never been before is suicide.
So what are your options? Well if civilization falls the only thing to do is rebuild from the bottom up.
What is the roadmap for building civilization? Security. In any God forsaken corner of this earth security is the number one priority. No matter how little you have there will be someone with less who will use violence to take what you have. Africa, Iraq, Afghanistan, the faces change but the story stays the same.
After security is nourishment. Food and water. If America falls no one will be dropping food packets out the back of C-17s in the middle of the night. Your municipal water supply will probably go tits up eventually as well.
Next is trade. Nothing makes civilization happen like the free market. Farms won't disappear, orchards won't die (except to protect the invasive Delta smelt). So that means transportation will be a must. People laugh at steam power enthusiasts now, but steam powered trains are a survivalists dream. Steam can be generated by burning pretty much anything and they can take advantage of the existing rail system. Too bad there aren't enough of them.
Rivers have been trade routes since time began, and transport barges are simple enough to build. Too bad there aren't enough steamships to get them up river. But even a small outboard motor can pull a few tons of cargo a long way.
I don't think that the US will ever turn into Mogadishu, but possibly Serajevo. Even London and several German cities maintained order throughout WWII. The economic collapse of the USSR was not followed by roving gangs of colander wearing barbarians. In Argentina and Chile things got bad but never TEOTWAWKI.
So have a plan. Stock supplies where you are or where you want to end up. Realize you may not be able to get where you want to end up. Civilization is a communal effort that the vast majority of people will work towards without much prodding. Our world has never seen a large city completely cut off for an extended period of time in the modern era. Back in history huge sieges during war would last for months or years, but even then the inhabitants usually found some way to survive.
Then again, if the system came totally crashing down and everything stopped most of us would be dead within six months. However, if it is only a financial crash things will look like the Great Depression. If it is an EMP attack things will look a bit different. If it is a plague then think Spanish Flu of 1918. Disasters, even man made ones, are generally survivable.
