they do not, i repeat they do not have metal detects, have not for about 6 months now. atleast they dont at the border crossing in san ysidro, the border in otay i dont know aout. but im sure about the regular crossing. i know this because i went clubbing two weeks ago and last week i just jocked 2 cycles worth across walking.

and the shampoo not a good idea...90% of the time if you are bringing something across that can hold shit, a piggy bank, shampoo even candles they will make you put it through the x ray machine.jocking it in some compression shorts is the best bet, you can fit far more then you think in your pants!i crossed with about14vials and two bottles of sit, yeah it was pinching the shit out my nuts for awhile, but it did the job. just make sure you have on a big shirt...not one that stops at the waist and you will be aight.

and if you get popped you will by US cops not tj ones, so you cant pay them off. and i dont know about other places but in cali if you get caught its a 5,000 fine and you have to pay 1000 within a month, secong offense is 10,000, third i dont know. gotta wait for another friend to get caught up.
