I agree with the concept of shelter in place. Most of my plans are get home contingencies. The point being made is there is always an exception to the rule. If you live near prairies large fields or forrested/wooded areas wild fires are always a concern. Other reasons to leave quick fast and in a hurry are, railway chemical spill, highway tanker spill, nuclear power plant disaster, riots in the streets, financial collapse, storm surge, tsunami, earthquake, industrial plant explosion, roving gangs, and the list goes on and on. Plan for the worst, hope for the best and be mildly amused by everything in between.
I am not giving up my property unless it will cost me my life or freedom to stay...in that case all bets are off. Color me gone and deal me out.
The point of this exercise is to bring about a mindset for reaction to your environment and plan ahead for all possible plausible contigencies.
I plan specifically for hurricanes and tornado weather (we get both). I also plan for other contingencies, but not to the extent that I plan for what has the greatest possibility where I am at.
For example we live within a mile of both the RR tracks and a major highway. A chemical spill due to an accident is a very real possibility. There are a great many pulpwood farms here. The possibility exists for wild fires due to both natural and man made occurance. Living near a large military range also means that in the event of a downed aircraft or dropped object leaving the homestead may be necessitated as well.
so if needed? Can you make it out? In less than a minute?
