Here is a population density map of the USA. I recommend you look at a full size one.

Now if the entire USA collapsed, FEMA plans to first distribute food and water to urban centers as 80% of US citizens live in urban centers. 40% live on coastlines.
Well, that would rapidly fail as in a collapse primary consideration is given to critical infrastructure.
Critical infrastructure - Wikipedia
These folks have to get first dibs on food, water, and medicine to maintain COG continuity of government.
Now looking at the map, pinpoint where you live. If it is a peak surrounded by peaks of densely populated population, then your chances of survival are low. If you live near a peak but where it is flat, the chances are migrating refugees will flood into your region.
Or if you are like me, you are FAR from the coasts with nominal peaks or even no peaks. There might be no need to bugout. If you did bugout then this is a worse scenario as you need seed, food, water, tools, and other supplies like medicine and shelter.
The safest way to bug out and avoid the throng is via rivers as you could bring supplies in a boat and follow the current and even use sails. In a pinch, what they did in history was have guys using ropes tug the craft from the banks. While other guys poled shallow sections or use oars.
If you live inland and if there is a qood aquifer and if the rainfall supports robust agriculture and you have at least two seasons of plantings to harvest, then you might thrive as the first settlers thrived who arrived in the West in Kentucky then Ohio then Indiana then Tennessee then Illinois then Missouri, etc.
