Just got the call from Mike telling me about his trip to a new mountain he heard about in New Hampshire. According to him the 5 hour drive to "Highland Mountain" well worth the trip. The place more features then Plattekill and Diablo combined. At the moment there's mostly intermediate and expert trails with more on the way. Basically, its open Friday through Sunday, 9am-5pm, $35 to ride for the day and $299 for a season pass.
