What are your main concerns?

[Steve]

My biggest concern is getting my family to my place. Once here, we'll be OK, but they are a long way away and travel will be difficult. I have to assume I will have to go out and meet them somewhere along the way, either because they have run out of fuel ( easy to fix ) or because ( more likely ) they have become jammed in a load of other traffic that has run out of fuel. Extracting them from a crowd of angry refugees will not be easy and will need good comms and tactics.
