What if the power went out right now? What do you have on hand to deal with:
Water
Critical meds
Food
Sanitation
You have to assume that the sewers would not be working or will back up quickly. Will that cause a problem if it rains?
In my situation, I would avoid bugging out like the plague - water and shelter are my biggest concerns, and I'd want to conserve fuel - because if there isn't any power, then fuel is also going to be a problem. Driving out to the middle of the desert is going to give me an issue with water.
At home, I have a 6000 litre water tank, and probably as much in a swimming pool. That's going to last a while. I can also scavenge water from other locations if need be.
We have no requirement for insulin, ventolin etc, so I guess we're lucky. Food - probably a good 2-3 months on hand if we stretch it out.
Sanitation - that's probably the hardest part, but I could probably build some kind of septic system up without too much drama.
Comms - I'd assume that mobile & land line comms are out. I have 5W VHF/UHF handhelds and I have solar power to keep stuff charged. A SW receiver, and a couple of 2-way satellite communicators (if they will still work).
For cooking etc, I have all my camp gear, gas, wood etc. Lighting I have gas and 18650 lithium based lights. Fuel for cooking would be a concern - I probably have 3 weeks worth of gas, and I have maybe a weeks worth of wood, but I have a chainsaw and handsaws and know good sources of wood that few others would know of or have the ability to harvest. I also have likeminded friends locally, so pooling resources would be a certainty.
The big issue would be what would happen after the first 3 months when food starts getting scarce, and upto then when others start getting desperate...
