One possible way to beat the system -- travel with young kids. My wife and I have been on about 12 flights since 9/11 and we have never been selected. Could it be the presence of our 5 and 2 year old kids?</font>
I have seen families with young kids selected numerous times, most recently at PDX on July 3. I think at PDX they do this because its "easier."

SFO seems most interested in the physically challenged and elderly.
