As Poppy said, nothing sharp...that means no nail clippers, no tweezers, no nada. I think that is their main concern...at least as far as I'm concerned.

You can take film and stuff, but I think if there is stuff on it and you send it through the x-ray thingy in the security area, the film can get erased. I know they have signs right in front of there though.

Also, don't get stressed if someone stops you and asks to check your bag...in my experience, they just kind of pick random people and search through your things. A security guy stopped Josh last time we were at the airport just before we were about to get on our plane. Although, I'm not complaining...I'm glad they've stepped things up.

My last bit of advice...don't wear a bra with underwire!!!! When I went to Chicago for the 2004 New Years, I made that mistake. I had to walk through the metal detector about five times before they decided to pull me aside and use the hand detector on me. We finally figured out it was the underwire in my bra...

Oh! And, I'm not sure if they do this everywhere, but the security people at the metal detectors had you remove your shoes if they were closed toes.

Hope this helped!!
