It was done by Mason-Dixon so it was a real poll, but it did seem to have a fair number of non-obvious questions...the garage door one is a toughy; it was obviously designed to produce a result for those who contracted for it.
Still, there's obviously a lot of ignorance. To me the big problem is the Saffir-Simpson scale (1-5) "backfiring;" I CONSTANTLY see people interviewed when a hurricane is approaching with that base their evacuation decision on what Category the storm is, which is incredibly stupid; on multiple occassions storms have gone up 2 categories in a few hours right before landfall.
Hurrican Alicia was almost 25 years ago, and it wasn't huge when it landed. There are a lot of young adults here with no memory of that whatosever.
It's complacency, fueled by a lack of historical perspective, that is the killer. Floridians should be a little more attuned to it this year, but I wonder if anyone else is.
