As a valid holder of an I-194 waiver the least of my worries when conducting US travel is whether, or not I want the low-tech fondling or high-tech pornography screening now available in most US airports. Either seems petty compared to the indignity of being shifted through secondary screening. That said, the Oklahoma Daily has a well-written editorial about the current state of airport security. Read the article, A nude awakening – TSA and privacy . The fundamentals of this column apply just as well in Canada (we have undertaken similar security screening measures) as they do in the US.
