A man's eyes can be seen above his high stack of luggage as he waits in line in the secondary screening area to be checked by Customs and Border Protection at Washington Dulles International Airport on Thursday, Feb. 16, 2012. Most people with this much luggage get flagged for secondary screening, because they are likely bringing in foodstuffs, some of which may be forbidden. (Barbara L. Salisbury/The Washington Times)
