a day trip to a neighboring country with yer stash duct taped to yer inner thigh groin area works much better.
Or in plain site, I remember someone who had 100k of computers strapped to the roof of a car back in the day whose appearence suggested coke and guns, the border flunkies almost took the car apart to detect the guns and drugs someone was obviously smuggling, even looked in the computer boxes and were pissed that they didnt find anything then waved me on my way :-)
