DOVER, N.H. (AP) _ A long-distance swimmer has braved frigid ocean waters in a nearly 4-mile swim in New Hampshire to raise money for a Maine wildlife medical clinic and education center.

Gary Sredzienski made the 3.75-mile swim in near-freezing waters Saturday afternoon from Durham to Dover in New Hampshire's Great Bay tidal estuary.

Sredzienski has made six cold-water swims in the past four years to benefit different nonprofit organizations.

This year's goal was to raise $10,000 for the Center for Wildlife in York, Maine.

Saturday's swim took Sredzienski just under two hours, while wearing cold-water gear to keep him warm.
