"Yeah - but one doesn't expect to get stuck because the town next door closes a public roadway"
Anthrax/Smallpox scares in 2001 inspired me to map out an escape route from my city to a relative's safe house 50 miles into the rural country without passing through any towns.
From that point there's another route I mapped to a secondary location 200 miles further out.
I bought the county road atlas for my state which shows topography as well as roads. I've even got contingency routes for doing the trip on foot if need be.
Three years ago we could have left on this trip with one hour's notice, either by vehicle or food. It would take me a day or so to get everything together now.
either by vehicle or food=either by vehicle or foot.
