From Bryant’s Maritime Blog:
The US Customs and Border Protection (CBP) issued a news release stating that, in an attempt to smuggle drugs across the US-Mexico border, criminals have adopted the practice of “navigating in sewers.” A suspicious person was observed in the sewer in Douglas, Arizona, located on the border with Mexico. When approached, the individual fled by wading through the sewer toward Mexico, leaving his things behind. The objects left behind included a 55-pound bundle of marijuana, a wet suit, a swimming mask, and a scuba tank. (2/26/10).
Note: There was no word on whether the Douglas sewer system is considered to be part of the navigable waters of the United States. Assuming that the sewer is dark, should the “vessel” have been equipped with lights? Is this a new challenge for the Coast Guard?
