You know you can opt out of those scans? I do it all the time. I'm sure you know, but in case, it's no big deal to opt for the pat down. Just show up fifteen minutes early (yet it has only taken at most an extra 5 minute for me -- many times faster e.g. when a false positive on the machine shows up and you're instantly considered a terrorist even if you're a 45 year old fat ass going to the beach).
