Jim Harper left his hotel early Thursday at 5:30 a.m. to give himself more than two hours to clear security at San Francisco International Airport. It wasn't that he was worried the security line would be long, but because he accepted a dare from civil liberties rabble-rouser John Gilmore to test whether he could actually fly without showing identification.

Gilmore issued the challenge at Wednesday's meeting of the Department of Homeland Security's privacy advisory committee in San Francisco.

This is interesting. A member of the DHS privacy advisory committe takes Gilmore's challenge on and sails through SFO. Some of the comments attached are interesting, as well as Edward Hasbrouck's blog post. Apparently if you want to fly without showing ID you just tell them you lost your wallet and they have a process for that. Its when you start yammering about the Constitution that they fuck with you.
