Sigh - I'm so boring. I don't leave it up to any of you any more. Life's too short; my time is more valuable & I have others to thank for protecting my liberties. Yes, Spiff will think I'm a wuss - I don't care.
I carry my nice F class LH slippers & take my (slip-on Cole-Haan) shoes off & put the slippers on in front of TSA. I pass through 'clean' (ie, didn't alarm the machine & don't have to take the slippers off), so no SSSS or any hassles.
And actually given I'm normally waiting for the bizness nimrods (as well as tourists) in front of me to empty their pockets (and they SAY that they travel a lot), it takes zip extra time on my part on either side.
Cheers.
