New border crossing question?

[g man46]

I am going to LOW next June and have gone on Oak island for many years. This next year we are staying on Bell Island in Canada. This presents me with a question. If we buy our bait and alcohol in Canada, and then cross back into MN (NW Angle)and then back into Canada where we will be staying, is this legal? Or...what should we do to be legal?
Thanks,
Greg

This is my my understanding:
You can buy bait in Canada and cross over to the US as long as you have the receipts showing that you bought the bait in Canada. Always have then with you to show were you bought the bait even if you are not crossing back and forth. If someone else has more info let us know. I am not sure on the booze.
