Northern New Hampshire's "Ride the Wilds'' network of 1,000-plus miles of interconnected off-highway recreational vehicle trails is open for the season.
A grand opening event for one of the largest such trail systems in the country was being celebrated Saturday at Jericho Mountain State Park in Berlin.
The final segment of the network's first phase opened in August, enabling riders to travel from Lancaster to Pittsburg.
Ride the Wilds leaders anticipate opening the second phase early this summer, to connect Northumberland, Star and Milan via an east/west connection.
All 15 towns within the trail system allow off-highway recreational vehicles on town roads along with some state highways.
