You being the cautious person that you are, do you A) take your car over to Cananda so your girlfriend can get $hitfaced at some club while you just sit there, and then come back to face the border guard, or B) tell your girlfriend nothin doing because you can't drink anyway and have seen what happens to nice cars on previous excursions to Canadia.
Which brings up another hypothetical situation. What would the border guard (wow that sounds intimidating) do to you if they found this drunken 19 year old, whom is legally underage in the good ole USofA and asked what are you doing with her and why is she drunk?
The reason I ask is because you were supposed to be hitching a ride with her sister as "the designated" and she has cancelled at the last minute with "car problems" and requests that they go in your ride. Even when you have a minivan to use, it just "wont quite be the same," without your ride.
So what do you do? Bite the bullet and take em. or play it safe like the pansy a$s you that you are!?!?!? Well, c'mon sissy! I'm waiting for an answer. Namby pamby.
