I dont consider myself a beginner but this is a very beginner question... I'm taking my 5D to San Fransisco tomorrow, do I need to avoid any xray machines or anything? I've never traveled with good photo equipment before. I plan to carry my camera bag on, that just seems like common sense, but beyond that is it safe to be sent through the security line scanner like laptops? Any other airport advice dealing with photography stuff is welcome. It's just digital, no film. Please and thanks for the help!
