I haven't riddled out the proposed changes yet, but seems special event permits for groups larger than 50 are being proposed for NH state lands.

What do NH race/fun ride organizers currently need to do for State land events?

"The Department of Resources and Economic Development (DRED) is proposing to amend and change some of the Administrative Rules. DRED will hold 5 public meetings and have a public comment period. Public comments can be sent to rulescomments@dred.state.nh.us or mail to DRED-Div Parks and Recreation, PO Box 1856, Concord, NH 03302 by October 24, 2013."


2 public meetings remain: 10/8 in Lancaster and 10/10 in Hampton.
