sorry, you should have said the desolate wasteland of western canada(calgary) I thought you meant california, from what I can recall, if you have a full box of rock they might not let you even put it in cargo as it will be too heavy, and definatly not let you bring it as carry on, too heavy,(unless you pay extra) if you do mannage, make sure you get extra heat packs and seal the box well of they will complain of the stench even if its cured, personally its not worth the hassle if you ask me, get it shipped greyhound or some other way... better yet buy from a decent local store, the rock wont be any different over here....
