The Allegheny National Forest in northwestern Pennsylvania is opening 365 miles of snowmobile trails on Friday.
Forest Supervisor Sherry Tune says recent snows made it possible to open the trails. Registration with the Department of Conservation and Natural Resources is required.
Tune said the only trail that won't open Friday is the Snowmobile Trail Connector No. 12, which is flooded.
The forest service and local snowmobile clubs will groom some of the trails once the ground freezes and more snow falls.
