Las Vegas here I come

It's official; I just wrote the check for the registration and bought the non-refundable airline tickets. I'm going to the FCF Convention in Las Vegas the end of July.

I have 6 weeks to figure out how to get through airport security without getting sent to Gitmo or having my stuff taken away or destroyed. Any advice will be appreciated. I'm traveling with an expensive camera that I'm not letting out of my sight. I also intend to travel with some things a normal human being travels with, like nail clippers, so I'll have to check a bag, which I've never done before.
