Canada to US border crossing

Went into Canada last month with twice the allowed beer and wine which I told them I had. After the usual any guns or ammo he asked if we had friends in Alberta... no. He asked if we were going to sell any of it... No and we were allowed to enter without paying any duty on the excess. Several years ago we were searched and required to pay the duty on the excess wine.
Entered the US yesterday on 93 into MT without any problems as we did not have any fruit or potatoes.
