Anyone had this before? Was flying through Denver CO, left the airport for a few hours - left stroller in trunk of rental car. Came back to the airport and going through security for next flight - TSA wiped down the stroller and found traces of TNT :-) They went through every single item of ours and wiped everything down and patted me down (I mean, really patted me down :-))
TSA Agent said that they do a lot of blasting in CO to reduce avalanche risk and the traces get blown into cars setting off the alarm.
I was travelling with wife + 4 kids :-)
