The sucky thing is, you may be best off staying put until the xhaos slows down, then make the trip and find out if you have a family to come home to when you get there.
The goal is to stay alive, you are no good to your family dead. Some things will be out of your hands. Train your family to handle themselves is the best you can do for them. Id let them know now jn an event like this to not worry about me, just stay alive, and if i am, i will find them.
