We stuff our motorhome full of groceries before we leave (even veggies) because to us things are very pricey up there and if they are not, we buy them.
Once I picked my garden veggies/washed and stuffed all that I could fit into motorhome refrigerator; it was packed to the gills with veggies. At the border crossing, they began asking questions and had not gotten to any food stuff. They asked do you have mace. I said, no. Hubby says YES. WHAT? It turns out he had mace for use on bike against ravaging dogs (he's been bit several times). All attention turned to that and we had to go in and surrender it..which we did. Then we were free to go with no further inspections and a refrigerator full of garden grown veggies. Yet I've had tomatoes and lemons taken away other times.
