I'm heading into Mexico for a few days of R&R. I always have a Leatherman "mini" on me and was going to toss it in my checked luggage, but thought I'd check first.
According to the US Consulate...
Carrying even a small pocketknife may find you in prison for five years for possessing a deadly weapon.
Pretty strict laws down south...and it sure controls all the crime, doesn't it?
(Needless to say, the mini is staying home.)
