Fake
A buddy of mine forwarded a bunch of pictures and said they were from Katrina. He had been duped by someone. I'm not sure who starts this crap. I wish they would give it up. I forwarded it too thinking the pictures were cool. I forgot to put my normal disclaimer of not knowing the origins. Thus, I didn't bather telling people they were not Katrina pictures. They are just cool pictures of weather stuff.
It kind of makes me sick. I wish they would just leave well enough alone. Don't try to impress people with bullshit. It nearly always back fires. Go take a look at the pictures. They really are spectacular. Make sure you read the truth about them.
