it's time to run when you realize that it's too dangerous to stay where you are.
I am witness to an excellent example of this principle: my father-in-law's journey to the USA. In 1919, his mother to be was in training at the Russian Czarist court as a future lady in waiting. Events occurred and she and her husband decided to leave town, traveling across Siberia with the White Russian Army. Along the way, closely pursued by their PHRASECENSOREDPOSTERSHOULDKNOWBETTER. adversaries, they intentionally wrecked the sled containing the family jewels (literally), as they crossed a frozen lake; their pursuers halted to pick up the goodies, thereby allowing their escape. Sewing needles were invaluable as trade items for food in remote Siberian villages on numerous occasions.
My father-in-law was born in a small village near Ulan Bator, Mongolia in 1920, christened as Boris Bekaravich. In the next few years he traveled through Vladivostok, Singapore, and Seattle to arrive at Hollywood High, Los Angeles, where he double dated with soon-to-be movie stars and became a second lieutenant in WWII, now with a name now anglicized to Harry. Among other things in a long and eventful life, he was a sound engineer on the Ozzie and Harriet show. His mother sewed for MGM, notably working on the costumes for Gone With the Wind. Of course I feel his greatest achievement was raising the most beautiful and wonderful lady in the entire world, but I am not an impartial evaluator. We lost him a few years ago, and we still miss him...
Lessons to be learned. When bugging out, take items that will be useful for trade, and be prepared to take drastic action to secure your major objectives. Who knows how long the road will be?
Of course, traveling inland a few hundred miles to avoid a hurricane may not require effort of this magnitude...
