IAD is my home airport - I am a experienced (over 1 mm on UA) but moderate level flyer (~10-12 departures a year) and I can honestly say I have never had a "bad" experience with TSA at IAD. Or any other US airport for that matter. Maybe I am just lucky....

I certainly don't agree with all the rules (shoes off, laptop out, liquids/gels in my baggie, etc.) but I know the rules and follow them and have never had a problem. I tune out the "yelling" and am prepared to go thru the security line when it's time. I pretty much dress the same on each flight - I know what items will not set off the metal detector and I think in all my flying I have set it off less than 5 times....

Now I realize that I dont have some of the extenuating circumstances that some do (medical issues, etc.) that maybe cause some of the problems.

I'm kind of neutral on the WBI issue - but never have had to go thru one or have a secondary "pat-down"
