Southern Maine seems to have a strong trials presence in the Berwick area,
and Stu at Jack's Cycles (also in Berwick) http://www.jackscycles.com/
can let you know of what's up in that area. I've a friend in the Augusta area who has many , many acres of sections and trails he's been working on. Problem is I enjoy helping him work on trails and sections more than riding my Beta. Any other trials riders in the Kennebec county area? If I can find someone who is even more inept than me, that could be enough incentive to ride.
