New Hampshire Underground
The New Hampshire Underground (or NHFree) is an organization founded by residents of New Hampshire devoted to pro-liberty political activism. It is headed by Russell Kanning, editor of the Keene Free Press, who moved to New Hampshire as part of the Free State Project.
The organization uses non-violent forms of protest, such as Social Security Card burnings, throwing snowballs at federal buildings, and public funerals for the United States Constitution. Their slogan is "the quiet revolution has begun."
However, on occasion their non-violent tactics have lead to arrests. On February 08, 2006, Kanning and his wife, Kat Dillon, were arrested for carrying protest signs against Eminent Domain.  On July 27, 2006, Kanning was arrested for passing out fliers to IRS agents on federal property. After refusing to appear in court on this charge, Homeland Security agents raided his home four days later, arresing Kanning. 
A number of its members, notably Caleb Johnson, support the eventual and peaceful secession of the state of New Hampshire with the federal government of the United States. The proposed name of such a state would be the Republic of New Hampshire. In 2006, Johnson created a website  to advocate such a plan.
