Continuing last year's exciting twist on the organization's annual Father's Day activity Ride the River, Davenport's River Action will again host hours of outdoor fun in Ride the Island, a June 21 opportunity for cyclists to ride the roads and trails on the Rock Island Arsenal while exploring its rich history and visiting iconic landmarks.

Delivering a blend of local history, environmental issues, education, entertainment, and fresh air, Davenport's River Action will again present a series of outdoor presentations in the first month-plus of the annual Channel Cat Talks and Riverine Walks: weekly "Explore the River Series" programs that, from May 26 through June 27, will address such topics as raptors, barges, Modern Woodmen Park, and the historically wicked night spot that was Davenport's Bucktown.

Featuring more than 24 large-scale, immersive kaleidoscopes created by world-renowned artist and Davenport native Tom Chouteau, the traveling exhibition Kaleidoscope Odyssey will be housed at Davenport's Putnam Museum & Science Center through September 7, this fascinating walk-through event designed to celebrate the intersection of visual art, science, and optics.
