By the way, I just read an article in our local paper that said the FAA may lift the ban on liquids in carry ons as soon as next year! Back to the good ole days!

Can anyone explain to me why you can't bring in any of these duty free items in via a land border. I think I know the answer is also "Only in Belize" but.......

I am not sure about if you enter another country via land, whether or not you can bring in duty free items. For Belize, anyway, and even going into Mexico from Belize, there is no duty free shop, therefore, there are no items to buy "duty free".
