In issuing regulations that take effect April 20, the National Park Service acknowledged Tuesday it was trying to pursue a middle path. Under the Park Service regulation, Jet Skis will be banned in 66 parks, recreational areas and seashores, although in many of those areas the craft have not been used widely. At the same time, the agency said Jet Skis, and similar personal motorized watercraft, may continue to be used at 10 federal recreational areas where water sports traditionally have been a focus of activity. The area where they are being used most is in Bird Island to the Intracoastal Waterway in the Laguna Madre. All rights reserved.
