Good grief, what a pain. It reminds me of when we went to Hawaii. I did buy plants but shipped them all home. When we got to the airport the agent asked if I had any live plants (he did not ask my husband) and when I told him "no" he asked again and mentioned I could buy legally inspected plants at the airport gift shop. I repeated I did not have any plants and he proceeded to inspect my luggage. Before I got on that plane my luggage was inspected 5 times. Someone was sure I was trying to smuggle plants. DH was hysterical and said I obviously had the look of a plant smuggler. Maybe a dog had picked up a scent of plant material because I often do have plants in my luggage.
