The fourth floor of the Statehouse will become an ad hoc gallery with the 32nd annual Idaho Watercolor Society’s Rotunda Art Show. You’ll see the work of more than 90 artists from across the state, including Anne Sorensen (“Rainbow Bridge”), pictured, who employ this difficult medium in a wide diversity of styles and techniques. Each year, a portion of sales helps fund the society’s Ruth Clark Scholarship for Idaho college students. The show is free to see any time the Capitol is open.
