Those who defy evacuation orders (or drive into waters despite warning signs...you name it) put others' lives at risk. I bow to those who rescue people. One part of me says there should be no rescue efforts where people choose to ignore evacuation orders, and this should be communicated way before storm season. Resources are needed to help those who can't help themselves, older ones, nursing home residents, etc.
Having said that, I know second hand (my parents) something about how difficult it is to evacuate. They evacuated (under orders) from the So. Carolina coast 3 times. Only once did damage occur to their place, and it was very minor. The third time, when they got to sis's home in Charlotte NC (about 12 hours on the road, bumper to bumper inching along, not sure where they pee'd...didn't ask),the worst of that storm was pummeling Charlotte (inland), way worse than what went on at their home in So Car.
Then you wonder, what do you take with you, and what do you leave behind? Can be very distressing. What about your g-mom's china or other prized possessions? Other than some clothing and survival stuff she settled on photo albums. Of course those had a lot of really old and unreplaceable photos, not like the digital stuff now. I remember her saying "next time, I'm just going to stay and take my chances." They didn't experience another storm to test that conviction. They were law abiding folks so who knows. But evacuation is not so easy, as I'm sure many here know very well.
