I am driving down to the Yucatan from the US. I plan to cross at McAllen Tx. (#1) How much alcohol can I cross the border with in my passenger car? I have carried 3 or 4 liters before in checked airplane luggage but I am hearing 1 liter per each 18 yr old and some crossings can be different. I plan to be in Mexico for a month or so. My Canadian whisky can't be purchased in Mexico so I want to bring it....(#2) Where do I purchase Mexican car insurance? My US company does not sell it for foreign travel. Going into Belize I purchase it across the border in Belize. I think I heard here it can be purchased in Tx. before I cross over. And do you have a preferred company? Thanks in advance.
