Comment "re: anyone flown into here from Canada?" on Watertown International Airport, United States

Watertown is no longer listed on the CBP web site as an airport of entry: http://www.cbp.gov/xp/cgov/toolbox/contacts/ports/ny/

Customs may still be willing to drive down from the bridge, but there are nearby official options at Alexandria Bay (89NY) and Syracuse (KSYR).
