How far away is Home ?
Look at where you live. If you have children and live more than a 30 minute drive from home then you are going to have to move home closer to work or get a job closer to the house or work from home.
If they hit us with a worst-case scenario an EMP in middle of January communications and sources of heat will not work.
Even if your car starts how much gas do you have ?
Walking home or to school / daycare will be the only option wearing your coveralls and boots from your get home bag in the middle of the day when the sun is out.
