Hi so we take off bright and early tomorrow morning for PDC (woohooo!!) have a question.. So we wanted to bring a pepperspray in our checked luggage, TSA said it was fine so long as it was under 4 oz and it had a switch to turn it off, BUT im trying to find out if this will be ok once we are in Mexico?? Tried calling the customs # i was given but they are closed.. has anyone taken pepperspray with them?? ALSO we have a 3 inch pocket knife I know the rules on packing that in our checked bags but also have the same question about whether that will be permitted in mexico and/or at the cancun airport. The LAST thing we need on vacation is to accidentally break a law and end up in trouble! would greatly appriciate the feedback, only a few hours away!!
