Duty-free liquor

[Lallans]

Since I travel in the opposite direction when going 'abroad' all I can contribute is that, somewhat depending on the State, hard liquor is immensely cheaper on the US side than in Canada, and sometimes the available bottles are larger too. How that plays out at the duty frees is possibly another question. You may be able to ask them, via Google or whatever.

But, curlers drink? I had no idea.
