This is probably going to be considered a stupid question but anyhow....Often when I return from NYC to the West Coast, I'll bring along a bag of pastries from a favorite bake shop in NYC. I always put them in a large paper bag to carry onboard since packing them would end up in a mass of crumbs if checked. Does anyone have an idea of whether this will prove a problem going through security, i.e, security handling them or my being forced to leave them behind?If you have any experience with something similar or any suggestions, info would be appreciated. Thanks!
