I was watching CSI:Miami last night and they had a 30 foot tsunami (if you didn't see the ep, it was one of the most unbelievable of all time) Anyway, they had lots of flyover damage pics and even I can tell there wasn't nearly the damage that a 30 foot wall of water would cause hitting Miami Beach... or anywhere else.
Question is... the damage shots taken from the air - did they use post Ivan footage? Charlie, Jeanne or Frances footage? Or did they CGI Miami? It actually looked at times more like minor damage - windows blown out, roof pieces missing than what I've seen of the worst of Ivan pics..
I've been to both places but not enough to actually recognize less obvious places.
