i always wrapit up in a plastic bag w/ a USED bouce(dryer cloth?) and slip it a sock and bury it somewhere in the suitcase. maybe not such a good idae to have it on your person? i know a guy who works for the tsa at Logan and he says there more concerned w/ bombs than pot so no metal. i had another friend who got caught at Logan w/ a pipe in her purse. they took it away but didnt do anything else needless to say she was a bit freakd and wont make that mistake again! bad idea. i think to carry a pipe because of the smell anyway
