I ride out there a couple of times a year, usually in the late fall, and mostly on the logging and forest roads. they are really quite nice and you can get in some serious miles out there. the last time I rode the MTB trails, it must be at least 6 years ago with Peter Minich, there were lots of trees across the trails. I don't believe that any of those trails are maintained any more. about a month ago I rode up Sawyer River Road and then out the old RR bed & snowmobile trail through the swamp to the Millbrook Connector. From there you could ride all the way over to Rob Brook. In fact that was a popular ride BITD.
