House Concurrent Resolution No. 21 declares 2026 as the Year of Volunteerism and the America250 in Idaho Service Challenge, aiming to engage Idahoans in celebrating the 250th anniversary of the United States. The resolution encourages citizens to reflect on the principles of the nation’s founding documents, participate in community service, and sign Idaho's replica of the Declaration of Independence, which is displayed in the state capitol. The initiative also features the Revolutionary Spuds, mascots created to make history engaging for all ages, and promotes the theme song "Forever Idaho," which celebrates the state's landscapes and communities.

Additionally, the resolution calls for the Idaho Department of Lands to plant trees as part of the Liberty Groves: Roots of Freedom initiative, symbolizing liberty and unity while preserving Idaho's natural and historical heritage. The goal is to inspire Idahoans to collectively perform 250,000 acts of service leading up to July 4, 2026, fostering a spirit of community and patriotism as the state joins the nation in commemorating this significant milestone.
