Worst US/Canadian border crossing

Crossing from Quebec into Vermont in our old minivan we weren't even questioned but they had a dog out sniffing the entire exterior. At the time our two sons were teenagers and sometimes used the van. I remember saying to my husband, "If that dog finds so much as a seed, someone is dead!" Luckily for the boys we were waved through.

Also remember as a kid coming into US through Detroit. It was my parents and us 5 kids in a big old station wagon. This was before seat belts in the back. My father put the seats down and told us all to lay down and pretend we were sleeping.
