Time to access the infinite wisdom of CP again....
I'm making a trip down the good ol' USA come December and I'm trying to remember the whole customs thing....what airport do I go through customs at? For example, I fly from Calgary to Minneapolis and than Minneapolis to Nashville. I'd presume I'd them in Minneapolis or Calgary? I guess my concern is on the way back, I go Nashville/Denver, Denver/Calgary....I only have an hour waitover in Denver, is that when I have to go through customs/immigration?
So confused.
Help...someone...
