Some decades ago, I had some BC peaches with me visiting Spokane. US Customs was fine as long as you had no cannabis
Returning to Canada with very few peaches, I was asked if I had any fruit, declared the remaining peaches which were prohibited entry even if from BC and directed to area with picnic tables to eat same and to use provided bins for the rest.
My current preoccupation crossing the border both ways is not forgetting to declare the bear spray. I was lectured not to have it in my hand, so best on the dash below the windshield.
