Last Thursday, wife and I were to fly to Baton Rouge for BIL's birthday, and to see SIL who had knee replacement done. I packed two bags of biscuit mix and a pack of country ham in my suit case. Told TSA about them and asked if I needed to remove them. (They ARE NOT on prohibited list!) Scanner said they needed to open suit case, which I didn't mind. Little wand when rubbed over biscuit mix came back positive, so I had to consent to a full body search, including shoes. First they x-rayed my shoes (again as they had done them earlier when in line.) Then they had to "test them." All results were clear, but still had to do full body search, which took several minutes. Finally I asked scanner "Wouldn't be easier if I just took my clothes off?" They cleared me, but I reminded them that I needed my shoes back. Took them a couple minutes to figure where they had put my shoes. Last time I took biscuit mix, scanner said that was the brand she used, and we went right thru. One airport TSA is over careful, and return flights from another TSA is a joke. Oh yeah, we didn't make flight as wife became SICK while waiting to board. When you are SICK, they don't want you on their aircraft. Come back another day!
