also, i flew through DTW a couple of weeks ago, and while waiting in line i said to my wife something to the effect of "oh, they still have the puffers here". the TSA guy next to me heard what i said and got chatty (he looked incredibly bored). he said that DTW was in the process of getting all new equipment. he mentioned the backscatter machines specifically. he said that the staff was being trained and that the installation will happen 'this summer'.
he was pretty friendly, which makes him the exception at DTW. at no other aiport have i been hassled, yelled at, touched and menaced like at DTW. the staff there is, for the most part, the rudest and angriest i have ever encountered.
(sorry of the aside... continue discussing DCA...)
