Where are you? Why would you need to bug out quickly? Bugging out is only preferable to digging in when staying means you will probably die.

You are NOT bugging out by foot, pure and simple. You have no non-vehicle mobility to speak of, you are better off figuring out WHY you might need to bug, and know how to tell when it will be needed. Then and only then, bug early. This is totes of stuff tossed in the trunk. Skip the tent- the wheelchair means you are needing to have a destination picked out, not found. You will want a family member or friend who you can stay with, or a public shelter.

You have a bad set of conditions. But the other choice it leave people behind.
