You mentioned leaving notes at each location.  That is something that occured to me when the events of 9/11 were unfolding.  My best friend and I were going to bug out of the Washington DC area with our families.  We were just going to head west on a state highway thinking the interstate would be packed.  I figured I would leave notes for him at every city we come to along the way.  But the way I was going to do it was different and I would like to ask what others think about it.  I was going to leave notes near the front door of the first McDonald's in every city we came to on the sidewalk in chalk (out of foot traffic).  This was a spur of the moment idea.  I planned on just putting the time I was there and the direction I was heading.
