This guy BULLDOG 75 is an idiot...
Right off the back of the US Customs Form
" The transportation of currency or monetary instruments, regardless of the amount is legal, However, if you bring in to or take out of the Uniyed States more than $10,000 (U.S. or foreign equivalent, or a combination of both), you are required by law to file a report on FinCen 105"...etc, etc
He should do his homework before telling everyone what he thinks he know,, post FACTS.
Oh and when you go into the back others do not know what you are doing... why would they follow you.. again IDIOT..
